These hate filled people are resentful of the progress that non-white americans are making and see their own lot in life declining. If you check out their websites, you will see that they idolize Islamic terrorists and their methodology: everything from lamenting the fact that no white guys would have the courage to do what was done on 9-11 to mowing down people with a car. One hate site even calls for "white sharia". These people have "fanaticism envy" and aim to reach the zealousness of the islamic extremists.
