Look no further than its original purpose:

“The notion of political correctness came into use among C*******ts in the 1930s as a semi-humorous reminder that the Party’s interest is to be treated as a reality that ranks above reality itself. Because all progressives, C*******ts included, claim to be about creating new human realities, they are perpetually at war against nature’s laws and limits. But since reality does not yield, progressives end up pretending that they themselves embody those new realities. Hence, any progressive movement’s nominal goal eventually ends up being subordinated to the urgent, all-important question of the movement’s own power. Because that power is insecure as long as others are able to question the t***h of what the progressives say about themselves and the world, progressive movements end up struggling not so much to create the promised new realities as to force people to speak and act as if these were real: as if what is correct politically—i.e., what thoughts serve the party’s interest—were correct factually.” https://www.claremont.org/crb/article/the-rise-of-political-correctness/

So, in my estimation, “political correctness” is the left’s way of redefining moral values to suit their purposes, particularly when their moral values run contrary to established, tried and proven moral values. They do this by controlling ideas, which are symbolized by words. They can’t endure true, honest, raw and unfettered free speech, so they have to control the words we use in order to control the thoughts we are able to express, thus attempting to funnel our minds into their way of thinking. In other words, mind control.

Political correctness in action:

1. The BBC has dropped the use of the terms Before Christ (BC) and Anno Domini (AD) on one of their programmes and decided that the terms 'Before Common Era' / 'Common Era' are more appropriate

2. The European Parliament introduced proposals to outlaw titles stating marital status such as 'Miss' and 'Mrs' so as not to cause offence. It also meant that 'Madame' and 'Mademoiselle', 'Frau' and 'Fraulein' and 'Senora' and 'Senorita' would be banned.

3. Throughout several US councils and organisations, any terms using the word 'man' as a prefix or suffix have been ruled as not being politically correct. 'Manhole' is now referred to as a 'utility' or 'maintenance' hole.

4. Loveable cartoon rogue Dennis the Menace has been given a politically correct make over. BBC chiefs decided to take away his edge in the remake. Gone are his bombs, catapult, water pistol and pea shooter - and in their place is a simple boyish grin.

5. Spotted Dick - a classic English dessert has been renamed to avoid embarrassment. The traditional pud Spotted Dick has been given the title Spotted Richard, after UK council bosses feared the original name might cause offence.

6. A school in Seattle renamed its Easter eggs 'spring spheres' to avoid causing offence to people who did not celebrate Easter.

7. A UK council has banned the term 'brainstorming' – and replaced it with 'thought showers', as local lawmakers thought the term may offend epileptics.

8. A UK recruiter was stunned when her job advert for 'reliable' and 'hard-working' applicants was rejected by the job centre as it could be offensive to unreliable and lazy people.

9. Gillingham fans had begun to fondly offer celery to their goalkeeper, ‘Big Fat’ Jim Stannard. The club, however, decided that celery could result in health and safety issues inside the ground. As a result, fans were subjected to celery searches with the ultimate sanction for possession of celery allegedly being a life ban.’

10. In 2007, Santa Clauses in Sydney, Australia, were banned from saying 'Ho Ho Ho'. Their employer, the recruitment firm Westaff (that supplies hundreds of Santas across Australia), allegedly told all trainees that 'ho ho ho' could frighten children, and be derogatory to women. Why ? Because 'Ho Ho Ho' is too close to the American (not Australian, mind you) slang for prostitute.

11. Some US schools now have a 'holiday tree' every at Christmas, rather than a Christmas tree.

Saw nothing outrageous, why if this wasn't chit chat I'd unload a bundle.
Anyhow was Julius Caesar politically incorrect when he wiped out the Republic ?. Yes he was to begin with and then for a year or so after that, no he wasn't, it changes in the form of a pattern of events, sometimes the changes are short lived, that's what Brutus believed, history proved him right and wrong the Empire needs a Figure Head and the Figure Head needs a Republic but the Republic can exist without a Figure Head sometimes.

We once were discussing on OPP Edward Gibbon, maybe he can help us understand where political correctness came from, or maybe it was so vague maybe I only imagined it, political correct, who was telling me that, was it only a criminal cable of voices in my head, is my conscience out to murder them as they feast on the low h*****g fruit of ignorance, what to do?.

Hummmm, the tree will eventually grow out of their reach, meanwhile, - and correct me if I'm wrong, - the Roman Republic was a Greek thing and the Philosopher's of Greece (I'm quoting)

"the philosopher's of Greece deduced their morals from the nature of man, rather than from God. They meditated, however, on the Divine Nature, as a very curious and important speculation; and in the profound inquiry, they disputed the strength and weakness of human understanding. Of the four most celebrated schools, the Stoics and the Platonists endeavoured to reconcile the jarring interests of reason and piety.]

Socrates lived on the edge of political correctness and Platonism was founded by the Socratic era, yet Plato was all for Spartacus the first historical culture to record bromance (correct me if I'm wrong) and Socrates committed suicide to preserve his political correctness which the noble gesture did, noble gesture, due to the fact that he was ordered to recant or be executed as a heretic.

My point is that Socrates preserved his political correctness probably to the end of the human race, but the rigid enforcement of Spartan military procedures that was unequivocally upheld by Plato gave rise to bromance and then the State legislated statutes specifically for the vindication of sexual relationship between men, (I don't know about lesbian relations in Spartacus).

This seems to me like the student wanting to go one better than the teacher, so if that is how it started 2•5 millennia ago it probably means a pattern was established where the culture of conscience will murder the interloper on behalf of political correctness, in his mind only.

Thanks for the reply, I know it's a bit overboard, but I have dreams of walking the plank.

And if on is unaware of or disagrees with said sensitivities or differences... What then?

Rose and I disagree vigorously on whether Islam is an Abrahamic religion or not... Our interpretations of the Koran and understanding of Islam differ greatly...
Should she apologize for triggering any Muslims that might read her views?
Should I apologize? I am not a Muslim, do I have the right to speak on their behalf?

I refer to one of my oldest friends as a Pakjabi (Pakistani from the Punjabi region)... This horrifies most Americans and Canadians who hear me say it.. Yet is not offensive to my friend... Should I apologize for offending white westerners with my nickname?

Agreed... I ask far too many questions sometimes.. But how else can one learn?

I h**e it when I ask how I offended someone and they explain that my words weren't necessarily offensive so much ad the ideas that they represent

Then go on to explain the history of a word...
For example... Once while talking to a feminist I offended her by using the word history... 'history' is offensive to some women as it is 'his story'

This would be funny if it weren't for the fact that it came with a ten minute lecture and the demand for an apology...

History comes from the Greek word 'estoria' which means 'to seek knowledge' (If memory serves me corrrectly)

I did not inform her of this interesting fact...

My response was that we would start learning 'herstory' when there was something to learn...

Angry feminists sound like Loony Tunes when they get worked up
