These "pride" movements simply mean that people who have been given second-class status because of an unchangeable characteristic that they have had since birth aren't going to take being kicked around any more. There is no reason for "white pride" because we, as a group, haven't been kicked around based on being caucasian. Nobody has ever said anything to me because I have extremely fair skin, blue eyes, and sustain painful burns (my skin peels, which is gross) when I'm out in the sun for a period of time.
The only group that I am in that has sustained repeated abuse due to an immutable characteristic is that consisting of women. Females have been abused for millennia across the globe, by men of all skin tones, for the horrible crime of being female. I understand from a male Swedish friend (born, raised, and graduated from Uppsala) that Swedes have also made great strides in eliminating the social stigma attached to being female.
I will take part in a "pride" movement for women, but not for being of the caucasian race.
