you can't support the normalization of the usage of singular they/them pronouns and then say you don't support people who want to normalize it/its because it's "too weird," as if using singular they/them pronouns isn't clearly weird to a lot of people.
you can't refuse to acknowledge an identity because it's "weird," they're all "weird" in the eyes of cisheteronormative society. people who use neopronouns like it/its, ze/hir, xe/xem, thon/thons and others don't deserve to have to settle for they/them if that's not what they use. it doesn't matter if something is "weird" or not. let go of the compulsive need to assimilate and just let people express themselves freely
