White people don't like that the language is gendered, so instead of Latina (female) and Latino (male) they told everyone they should be using Latinx and it stuck.

I've seen a number of Hispanic people get irritated that people are trying to take away from their culture and language, and others that say they don't care.

It's an English term for Latinos that non-Latinos in the U.S. use to signal inclusiveness (usually gender inclusiveness these days, but its history includes some LGBT inclusiveness as well). You see it a lot in corporate emails about awareness and sometimes in colleges and academia. It's mildly disliked by several parts of the political spectrum for a surprisingly diverse number of reasons, but it's generally well meaning. https://en.wikipedia.org/wiki/Latinx.

It's a whistle to signal your tribe allegiance. The word sounds backwards on purpose, so it's not used by accident.

From Wikipedia: >Latinx is a neologism in American English which is used to refer to people of Latin American cultural or ethnic identity in the United States. The gender-neutral ⟨-x⟩ suffix replaces the ⟨-o/-a⟩ ending of Latino and Latina that are typical of grammatical gender in Spanish. Its plural is Latinxs.
