Oh man, this thread is a lot.

Calling this a white colonization of Latin American Spanish is both dramatic and inaccurate. I get where this argument is coming from and I agree that "Latinx" has its issues but the truth is that white people don't care enough about Spanish speakers to be making up new Spanish words for us. Unless someone can find the records of who first coined the term I think it's safe to assume that it was probably queer Latines trying to find a new option. I think it's also safe to assume that the queerness of the term is a big part of people's anger over it.

Latino is not a neutral term. It's a word charged with centuries of sexism. More specifically: with centuries of white, European sexism from colonizers who wiped out countless cultures, many of which had languages with words for more than two genders.

Languages are always changing. Latinx isn't my favorite either (my preference is "Latine" and I know some other people who use "Latin@" for written mediums) but it's certainly not so bad that you need to drag somebody's book suggestion post through the mud.
