"ratfucking"? Classy. I don't agree with him but I feel a bit sorry for him. He's passionate about this and he believes what he's saying. Perhaps nothing could make him see things differently, but banning him definitely won't.
I find it rather concerning that they're that quick to ban him for voicing dissidence. Was there anyone threatened by his speech?
For the sake of fairness, consider the case that people opposing him would use similar lunatic language.
They would drop fighting words like neoconservatives, greedy capitalist, far right nuts into the discussion. That would be crazy just as well.

For the record, I think ESR was mostly right on the issues. He is just communicating like lunatic angry person.
