Remember

White supremists and racists, react out of fear, frustration, ignorance and the rage that follows these things. 

They want to be special and the only way they know how to do this is by force.

They don't have the words, patience, or understanding to change things any other way.

Hit something, shoot it, shout it down, drive over it, knock it out of the way, the people around them suffer as much as the people they hate.

Eventually they are relegated back into the darkness they live in and they don't understand why.

And thank god for this ignorance, it is what gives the rest of us time to prepare.

But what we need to remember is that there WILL be another infestation. They may not have much going on upstairs, but it doesn't take much to crawl out of the woodwork and start chewing on other folk's lives.
