Latinx is an attempt at ungendering the “gendered” Spanish language. So no, it does not have a word for this white guilt abomination.

Frankly I think pushing so hard for this has absolutely backfired, and now it really just feels like we’re telling brown people how to speak god’s language again.

And this is completely anecdotal, but haven’t yet meant a Latino or Latina that hasn’t laughed at me when I ask about it. Stupid gringo shit is the consensus so far.

What's funny is that in Hispanic speaking countries we already had a work around for this - we would use @ when not knowing the gender of the subject we were talking about: latin@ could mean Latino or Latina. Of course, this does not have to apply to a person, and this all came around long before people's newfound sensibilities.

 The X addition was likely made by some neurotic, non-latino Tumblr activist that decided having a gendered language invalidated their identity.
