@emmett grogan,
This is quite a liberal site, you have to be pretty bad to get kicked off. Some people are very good at sailing right up to the line without crossing over.
The two individuals you have mentioned are ignored by a lot of people so they plumb the depths of depravity so they can be noticed.
There's lots of decent people here, don't let a few idiots put you off. The ignore function is a very useful tool.
