Yes, because your phrasing shows your lack of care around bigotry towards people who use neopronouns. Its misgendering plain and simple, no different than if you misgendered a transwoman or transman. It should carry that same weight. And if it doesn’t then you are not a trans ally because you are not supporting trans rights, just the ones that fit within your view of normalcy. Purposely misgendering anyone for any reason is insulting, disrespectful, and harmful.
That drama happened in part BECAUSE .world has a problem not moderating enough against transphobia.
