The Ironic thing is they are removing posts from conservatives and "non-progressives". I just read their stupid cowardly rules.
Have a look.

Rule 1 is all you need to know about why libs can't win in debate.
You know, I don't mind that they have their own message board (after all, we have ours, and we have been known to ZOT offenders). I do object to their hijacking of the word "progressive" - as though some logical and historical inevitability favors Socialism. The future is for freedom - and that's what we're fighting for over here - and over there.
