They are not trying to censor them, or tell them they can't be on the web, just to isolate them from everyone else. It is a very easy to follow page. The page gives listings of the hate groups in question, has links to their sites, and bios of the people who are involved in the hate groups. They give every side of the issue that they possibly can and add a few sides after that. As the other sites had, this one also contains an area to join them, send donations or just to contact them and give your opinion.

It is about time that it stopped, and it comes down to us to stop it.
