For real, I've looked into this and in LatAm some people prefer Latines as the neutral collective noun. I like that myself cause I'm down with gender neutrality but everyone thinks it's a fucking typo so I give up.
Outside of the Bay Area tech scene, I can't imagine I would ever use LatinX in Spanish conversation. I choose my battles.
I don't understand what's wrong with the terms "Latino", "Latina", and "Hispanic". These are _Spanish_ words, and we're speaking English, so it doesn't make much sense to invent new words just to appease the tiny activist trans community on Twitter.
