You might not want to block those who post about the "evil Jews" or the "stupid niggers". Continue giving them an audience, and remember:
Free Speech allows you to credit or condemn yourself.
The facts are with those who learn to read, not with those who write.
Hate also destroys those who hate.
So on, so forth.
Jesus taught us to love people no matter what or who they appear to be at the moment. You do not need to like them, agree with them - but you need to let Jesus deal with them.
Maybe in some time they come around, maybe they will never.
Glorify God by leaving all such decisions in His hands!
