I read a few articles, and I can understand the viewpoint about how using latino and latina can be seen as problematic. I understood that before. But I don't understand why we don't just drop the o/a at the end and use "Latin". No article seems to explain this, and nobody here in HN has explained it either. I'm not trying to be argumentative for the sake of it, I genuinely don't understand what's wrong with simply using "Latin", which would be linguistically more correct in English, and also a contraction of "Latin American". Maybe there's some cultural nuance I'm missing, as I'm not American. All the Latin American people I know identify as being from their home country (mostly Argentina and Chile), rather than Latin American anyway. The whole Latino/Latina/Latinx thing seems to be some Pan-Latin American thing for US residents, trying to amalgamate a whole continent into a single cultural identity.
