It reminds of an old joke:
Conservative: "I keep getting banned for my views"
Rando: "Oh, small government?"
C: "No, not that one"
R: "Oh, so fiscal responsibility?"
C: "Not that either"
R: "So which ones?"
C: "Oh, uh... You know."
That’s just watering down what hate speech is.
A) Harm the target, who has gone out of their way to avoid that harm already (by transitioning/changing pronouns)
B) Dehumanize the target in the eyes of others (this person doesn't matter, their wishes are to be entirely disrespected)
seems like a reasonable candidate for hate speech to me.
It's very silly to claim that this is some type of hate.
E: Removed the troll feeding bits.
