Right, I don't know situations in specific areas, I don't know how KKK operates, I don't know any single member of the klan. However, I'm not going to judge anyone just because they're members of some society. Further, I don't see anything bad about "White Pride". It sounds a lot like "Gay Pride" in some ways. To be proud of what you are, and there's nothing wrong with that.
You're making a strong assumption that KKK will, without doubt, harass the black upon sight. That's the only way I could be "mixing" unrelated issues, because that's the only way fear isn't the issue. I don't see this as "White Pride", harassment is always harassment, however I see it wrong to deny people their right to be proud of themselves, no matter what they are and who they are. Be it black, white, gay, pedo, whatever, everyone should have right to pride of who they are as long as they don't deny anyone else their rights. As of such, I believe there has to be good and fine people among KKK as well.
