Latinx comes from a gringo who never bothered learning fucking anything muscling in and telling you how to speak your tongue while pretending this is how respecting other cultures works to shut you down the moment you complain and you know they're not going to get it.

Understandable, "Latinx" is one of the most condescending terms I'm aware of.
