No One should post bigotted or intolerant comments, even if talking about the group you belong to because it is a generalization which is usually wrong and allows others to jump on the band wagon with impunity and say stuff like, "Even(insert group)think that other (insert group) commit more crime than anyone else."
So dude is pathetic, but blaming him for a societal issue does not help resolve the issue.
If everyone wants to see change (for the better) as they claim, they must first change themselves.
I see derogatory comments made by "blacks" on a constant basis, even when they use such comments referring to others within their group or other groups ("Cac" although short for caucasion has a rather derogatory implication to it).
Say what you will, but until we clean up our own act, don't get your feelings hurt because others mimic you.
