I'm a latino (US citizen, born in Latin America). Somebody said that also at my job. LatinX is despised by most Latin people living in the US. It's acceptance rate is less than 2%. Comes from a 'scholar' invention, and aside of the scholars with both hands in their ears that want to use it, almost all Hispanic and Latinos dislike the term, specially the ones living in the US. I compared it to using the N word with African American people. Call them something they want to be called, not whatever you want to call them.
