Back off.This is difficult to phrase; sorry if I come off as scolding or snippy. But like, come on, man. When you see a map of the single largest ancestry group in a certain area, and that group happens to be people of Mexican descent, your mind should not jump to this kind of weird, hysterical racialist fearmongering. Wolfram already covered why Mexicans show up so prominently with this particular format, but no, Hispanic people are not a plurality of all Texans, and they won't be a "majority at this rate" anytime soon either. Putting it the way you did sounds like you're scared that that's a possibility, and feeds into anti-immigration rhetoric. Again, like, sorry if that wasn't your intent with that message, and I'm not, like, calling you racist or anything, but it's difficult to read it with any other meaning.
Play the ball.
