Can i ask why I'm starting to see more openly far right white nationalist Hispanics of obviously mestizo ancestry?

Mestizo meaning Spaniard and Azteca or other indigenous ancestry of course. It really bothers me my girlfriends brother is like this (she's latina from Cuba). Plays up the Spaniard and Aztec part of his heritage and denigrates blacks and Asians.

Yes he looks like a 4chan user
