Oh, like when some random person who is just trying to get by is subjected to slurs based on some aspect of their identity.

I could take the argument you made in a parallel thread and say that people who feel upset at being labeled fascist or racist or sexist could just choose not to be offended. Why is the question of truth/falsity suddenly so important when it impacts them, whereas it's irrelevant when they wish to make satirical/ironic statements that may or may not impact others?
