Anyone who calls themself a 'proud racist' is speaking badly at least.
This uttering was one of those from people who don't know how to express themselves very well, venting his frustration over illegal immigration and the charge of rcaicm not by expressing his views but by this.
He didn't mean racist literally, he meant it as the word he disagrees with he's attacked of.
It's a very poor choice of words. Even his defender in the article says he's 'in no way a racist'.
Some of the citizens can't say as much though, crawling out from under their rocks.
