If that's the case, perhaps we should just use the words that mean the things we want to say, instead of using words that don't mean the things we want to say to say the things we want to say?
It isn't a great start when people leveling criticism at someone don't even understand(or care) about the meanings of the words they say.
Arguing that someone may be biased on the basis of their race is not racism. It's at worst generalizing or ad hominem. This had nothing to do with Curiel being Mexican specifically other than the nature of the circumstances (Trump might have advanced a similar argument about a Muslim judge, for instance).
Progressives going after this specifically was misguided overreach. There's a reasonable basis to assume someone may be biased by their racial heritage. There's so much else Trump has done that is totally egregious that I find it mind-boggling to call him on this specifically. If anything, it gives ammunition to the anti-PC crowd.
