Thats a bit ridiculous. How is this place humoring racists or cranks? Do you really only care about one side of a viewpoint? Then dont engage the other. I noticed people engage them repeatedly and then complain. Respond to the posts and posters you think are worthy of your effort. Otherwise, you must be enjoying the interaction with them to do so. You can engage whoever you want. You dont have to reply to anyone you dont want to. You cant be that easily ruffled.
