Some guy says "whites a superior" and suddenly there's an epidemic? Nah, the number of white supremacists has gone down big time over the years. I think it's down to below a few thousand in a country of 320 million.
Meanwhile, while Trump can certainly be brash and have a foul mouth, so does the rest of pop culture. I'm not sure why there is an outrage here. Democrats today are cussing up a storm, presidential candidates. They aren't ridiculed, but Trump is. It's pretty obvious this is just a media double standard that you're biting into.
