A lot of white people have been brainwashed that they have no culture of their own. Their own culture is never celebrated, it's always the culture of other peoples that they are taught to respect/celebrate/acknowledge. Showing any love for their own people, own culture, and especially if they show pride in their heritage, gets them labeled a neonazihatefilledracistwhoneedstodie. It can take a lot of effort to throw off this brainwashing. Billions of dollars have been invested into the propaganda to make them self-hating.
When stripped of their own culture, there is, naturally, a void there. To complete themselves they seek to fill that void with something. Now what is promoted as the pinnacle of civilization, the origin of all modern conveniences from peanut butter to street lights? That's right... black culture. So they choose that.
Thankfully many of them grow up, and grow out of that eventually, and find some peace within themselves to accept who they really are. Others never accept their true identities and continue to try to fill the void with other cultures.
I am disgusted by wiggers too, and I think they should pull their pants up, put their hats on the right way, and speak properly. However I do see why they got that way and that they are casualties in a propaganda war.
