I believe strongly in Free speech however it isn't “polite speech.”

Free speech isn't “speech I personally like.”

Free speech isn't “speech that doesn’t offend anyone.”

Free speech is the right to say things that're controversial, unpopular, offensive, sharp, firm, even rude, as long as they don't cross into direct, credible threats of violence, doxxing, targeted harassment, or incitement to imminent lawless action (Brandenburg v. Ohio, 1969).
