Its not any weirder than pretty much any other language. In many Latin languages the default is feminine rather than masculine. Referring to a group of mixed gendered people in Spanish would be default feminine. Theres literally nothing inherently incorrect about either one having a default. I would imagine most native Spanish speakers would view someone as stupid for intentionally making something masculine over feminine just to prove a point of any kind.

Seeing English having a masculine default is patriarchal in some way is just nonsense. Latin countries are no less patriarchal despite having a completely different kinds of genderization in language. I studied a great deal of feminism and gender theory in college but this is one place where I dont see the logic at all. Overall tho I could care less if people want to write whatever pronoun they want there. To me, having it be gendered is a very outdated method of writing and they sounds far more modern. Saying he or her where you could say they just sounds like old timey Atlantic accent speech
