It wasn't easy to determine the gender
When I respond to tickets from someone with a gender neutral name, I respond with "Hello," or "Hi Jackie,". Before this whole "declare your pronouns" thing we managed to do it just fine.
As I've said before, I couldn't care less about someone's gender identity. I've been in situations where I've been corrected and I go with it. If some guy wants to be ma'am or a girl wants to be sir, no skin off me. But the all these posers jumped on the bandwagon - "See me being all edgy? I'm xe/xim! I'm it/that!" It's stupid and I hate stupid things. Then they got to the point where they were demanding and obnoxious and belligerent, and I began to actively dislike them.
We all get along so much better when social activists aren't trying to cause friction. I hope we learn to start ignoring them and just treat each other with what used to be common courtesy.
