My problem (and many others I guess) is that i won't remember Pat or Kelly the next time. And the next time. And the next time etc etc. Especially if I only see her ever so often. No chance to remember special pronouns beyond what gender they present. He/she/him/her is relatively easy (but not always...) them/they or anything else they prefer seems overly complicated in a social setting.
But if I remember the name and intentionally use others to taunt you, then yes, I would be a cunt. And I try not to be one...
I wonder what would happen if you opened fire against these attempts? If you are not identifying yourself as law enforcement, one would fear for ones life and could open fire and protect oneself?
