gendered pronouns in general should just be phased out. we don't have raced pronouns and we do just fine. we don't have sexuality pronouns and we do just fine. we don't have nationality pronouns and we do just fine. No real reason to have people assume other people's gender whenever they want to talk about someone when gender is irrelevant to the conversation anyways.  it's not abolitionist, gender can still exist, just as race, sexuality, nationality, etc.. exist without needing pronouns for each. you only just specify each intentionally when you want. A benefit would be a reduction in the binary mindset and focus on gender in the English speaking world's mind.
