Sure it may be a matter of education as Lani states, but even someone uneducated could take some moments to actually think about what he is saying.
Personally I don't understand anyone who says he is proud of being black/red/white/green. I mean, having a color isn't so much to be proud of.
I make an exception for statements like this as an answer to oppression, where it merely is a statement to show that you will fight back.
I assume that when people say that they're proud of being <colorname> they think that this color stands for something.
So I would like to ask any forum member who also thinks he is proud for being <colorname> what this color stands for.
Andrew, as you started this thread (and yes, we already have a lot of posts without insults or other stupidities), if you want to say that you're proud of being white but you cannot do so because you don't want to be called a racist. What does being white represent? What does it stand for?
(try not to generalize)
