Hate speech is defined by Cambridge Dictionary as "public speech that expresses hate or encourages violence towards a person or group based on something such as race, religion, sex, or sexual orientation". To answer your other question, I think saying you're going to vote for trump is foolish but not hateful.
Saying that you're going to vote for Slow Joe Bribem, the man with no brain matter is an insult to pragmatic people in every arena of life. It actually shows a hatred for Americans as Joe couldn't know how to protect us from any foreign or domestic power that wants to overthrow our liberty loving country. (Which currently includes his and your marxist party).
