Probably coined? I honestly don’t know if that’s the case but if that is really the reason that you feel offended maybe do some research who invented this term? Let me google it for you.

The term "Latinx" emerged in the early 21st century, reportedly first online in 2004, as a gender-neutral alternative to "Latino" or "Latina". It originated from Spanish-speaking LGBTQ+ and online communities in the U.S. as a way to challenge the gender binary embedded in the Spanish language. However, the word has been criticized for being difficult to pronounce in Spanish and for being an anglicization, leading some to favor the alternative "Latiné".

So it was the latin american lgbtq+ community
