Sigh. You have no concept of property. This website is PRIVATE PROPERTY. The owner decides what he wants here, as much as you do in your home (or box, whatever). Where in hell do you see "free speech for all" on the main page? You don't. This is a conservative website, for conservatives (shocking). You're going to have to accept that you are not welcome to post here.
Also, please name an American that "went to jail" for expressing their views legally? D'oh, your a smoking hole in the ground, never mind.
Kinda makes sense ... if you've had something fall on your head.
