While this specific case may even be somewhat justified, where does it end? What constitutes an insult so grievous that the government should punish you for it?
Misgendering, alright. Attacking someone’s honor? Probably. Putting together an angry, slur-filled rant? Perhaps. Insulting someone’s parents? Hmm.
And so forth. This is an incredibly slippery slope, one that virtually all democracies currently existing have avoided to go down because it inevitably leads to oppression.
