The action by the Daily Kos is simply another example of the intolerance of the Left. They are a collection of petty dictators. They can't stand anyone who disagrees with them. From their perspective,disagreement with these self-named "progressives" indicates bad breeding, stupidity, and an evil nature. Anderson got banned because he didn't parrot the Daily Kos line. Would-be totalitarians.
The reason "liberals" despise Christians? Christians have God sitting on the inner thrones of the temple of their souls -- but liberals have themselves sitting on that throne, and they feel threatened and furious that anyone would dare challenge their own superiority by suggesting they challenge God.
And in response to your post -- this is why they cannot tolerate "dissent" or even "disagreement" of any sort and from anyone.
"Liberals" exist in the Kingdom of Self. How dare anyone challenge that "self" with a God.
You see, if the liberals were more honest, they would openly admit their belief in themselves as a "god". But this would muddy the political waters. If they were to be honest about their belief in themselves as a "god", in all fairness they'd have to be respectful of the God that others believe in and worship. So, they do the next step; twist Scripture. In their own worldview, it's a political thing.. this twisting and misuse of Scripture: They see it as undercutting their opposition.
