They can call themselves latinx and I would call them that as well, if that’s what they choose. The issue is with people (like my sister-in-law) insisting that everybody hispanic should be called latinx.
im just saying, those are the only people who I listen to on this discourse and I will parrot whatever they say, because my tounge absolutely defiles that language every time I try to speak it, and don’t think straight cis people have a right to an opinion here, regardless of their language preference.
