Nah, those people actually are usually much better at grammar than those against it (you know, the "I don't have any pronouns, I'm normal" or "they/them is for plural only" people), and they know you don't use 3rd person pronouns to refer to someone. Also they're usually content with being ignored by people who don't want to use their pronouns, I think that's just your wet dream, that they give this much fuck about you talking to them.
Had an it at a place I worked, it went be xhe xer never spoke to the person. I avoided it like the plague. I'm not walking on eggshells for small talk or whatever the case might be.
Fixed it for you.
Most of these People are perfectly comfortable pushing anyone that dissagrees away and surround themselves with People that do. Most arent even mad but kinda like the relish in the feeling of being a victim, ill never forget trying to apologize to a trans person whos pronouns i confused when drunk once, and the person just having this huge grin the entire time constantly finding new things to get mad at. If some lgbt People want their own bubble like that i dont mind, i dont want them in mine, any sane lgbt People are always welcome tho.
The world has a lot of problems as it is, stop making more.
Their presence in your life is mandatory by law. Forced diversity everywhere. They have to be included in workplaces of all kinds and businesses must not refuse servicing them. If certain groups try to exclude them they are shamed bullied and finally forced to case to exist by legal means. Ignoring them is what brought us here in the first place.
It's difficult when I walk through London and have to use a multicoloured zebra crossing.
