I'm not going to use 'they' to describe gender-neutral persons. I don't care if that's offensive.
Why don't you want to use the pronouns that people ask you to use when you refer to them?
I think it's annoying to have to consider what each person wants to be called. I'm tired of it.
I know it can be difficult to keep track of everyone's preferred pronouns, but it would be really considerate of you if you at least try to do it.
I don't care about people's pronouns and I don't want to have use "they" when I'm referring to a single person. I'm tired of being politically correct all the time.
It sounds like you're really frustrated, but you have to understand that people do not fit into distinct gender categories and they feel uncomfortable because they don't fit into a male or female classification. If you're uncomfortable using "they", try to refer to them by their actual name and not a gender classification.
