That is an interesting observation. I read a book written by a Freeper with the DC Chapter of Free Republic (who I met l personally on many occasions ) titled “Undercover Patriot” where she infiltrated a leftist group.
It was interesting, and the leftists behave in private exactly as you think they would!
We all know this to be true, because they speak and act one way when interacting with the public or non-liberals, but when they think you are one of them (as they often assume in certain situations) you hear them say things that are quite different.
It has been my experience that conservatives, for better or worse, are largely consistent in their outlook and the environment they inhabit or company they keep does not present a disparity.
