I'm not offended by the statement. I'm offended by the likes of 007 and Mud who are using it to whine. Racists are basically big whiners, and however the phrase was initially introduced, it was quickly coopted by the Klan et al and it is now their calling card.
THe act of censorship, makes their "whining" justified. It is valid to complain about censorship.
YOUR calling it "whining" when it is justified, is you supporting the censorship and the racism.
Whether this is from white supremacists or NOT, it was a brilliant ploy, and the liberals in question fell for it, hook, line and sinker, revealing that, to them, it is not "ok to be white".
