if we taught people that gender is an abstract concept, you'd probably see less hatred for xenogenders. 'How is your gender a dog that makes no sense' the same way your gender is man, or boy. Maybe I've just intellectually ascended or something, but the idea of someone being a pupgender neogirl just doesn't confuse me.
Stop treating concepts like 'man' and 'woman' as more solid than 'mushroom' or 'cleaver' in terms of gender, because gender in itself is abstract. It makes so much less sense to enforce the 'invalidity' of xenogenders because all these rules are made up.
