As others have said in this thread, it wasn't created by white people. That's why I'm saying this is inflammatory.
I personally think that choosing 'x' was a poor choice, and it's basically unpronounceable by everyone in both Spanish and English. But making up supposed racist origins is a bit much.
Do you have a credible source for this claim? All I’ve ever seen are vague assertions it originated “organically” in the early 2000s.
