My being mistaken, but at least having admitted it, has no bearing on your otherwise being full of shit and not admitting it. I know it's rare for you guys to harvest hay here, so make the most of it.
Most likely because the superiority of one group over another is so built in that is in the language structure.
So, you are agreeing that conservatives are superior to liberals? I suspected that deep down you knew this.
White men who are racist, most are republican. Among black men who are racist most are democrat. I know quite a few Mexicans I'll have to ask them. One old guy who has worked for me for 20 years is racist against whites is pro republican but will take a government handout if he can get it, kinda like republican bankers I guess. I'll have to ask some of my Mexican buddies about this and get back to ya on which way they lean politically.
Interesting choice of words in that "superiority". You've got the media on your side, that's the real reason.
