Good for you. You've established boundaries, as every person should. But, would you banish a friend because they choose to be friends with someone else or if they've spoken in support of someone else who is struggling to adjust to a rapidly changing landscape regarding gender? I'm sure your patience must be stretched to the limit on an hourly basis, if not more often. But, I hope you give some slack to an ally who is still on the learning curve, especially an old queer fella like me.
Interesting that trans folk are called "too sensitive" when they throw a shit fit over chronic pronoun misuse or being mis-gendered. Makes me wonder what adjective accurately describes someone who throws a shit fit on a plane over a crying baby? Certainly not "sensitive."
