Y’all is the opposite of offensive for trans people. I lived in the south for a while, and I now use y’all specifically to be inclusive. I wouldn’t say “you guys” is offensive to trans women, but I would say for me and likely other trans women it briefly brings to mind being misgendered in the past, so I would call it a small kindness to ube as gender neutral as possible.
I tried to post my void, but jerboa wouldn’t let me.
