I have literally only ever had problems with one set of neopronouns, and that was because they have cultural implications (“fae/faeself” kinda steps on the toes of some Celtic pagans and some of the Gaelic-speaking cultures as well, as the fae are dangerous and already hate people enough as is according to my research [I’m most familiar with the Irish mythos]). That is the only genuine set of neopronouns I have ever had issues with and I’ve yet to meet someone who uses them.
I’ll be so fr I feel fae pronouns are more about like, tinkerbell fairies than the fair folk. Like there’s a big divide between the idea of faeries in modern American culture, where I think the pronouns stem from, vs the whitethorn tree on the edge of town that you can’t cut down because the fair folk guard it
