If you are talking about Free Republic... I can't test that theory because I've been banned.
I think the majority of the active posters have been either banned or like me just couldn't stomach the place any more. It was bad enough when the place was a hate fest for for the McCain Palin ticket, but when a "Mormon" was the front runner a few years later, good god, the things that were alloud to be said about Romney, and anyone supporting his candidacy with their post was Intollarable. And not just politics. Religion was another place where one would get attacked horribly, without no attempt by Jim to throw water on it. One guy just after my dad died posted that he is in hell, because asking the Lord into his heart on his death bed was not enough, because he wasn't water baptised. He posted that on the thread asking for prayers for our family. That is how bad TOS got.
