Let me give you a libertarian answer... it's up to individuals to decide what their own identity is. When an individual identifies as one thing, and society refuses to accept that identity and imposes labels they find offensive, then they are being oppressed. And that's a much more substantial form of oppression than "Please don't say that" is.
I'm utterly shocked (not really) how many people proudly wave a flag of liberty, but are quite content for society to denounce and punish harmless individual expression, if they aren't comfortable with that expression.
