Advocating freedom of speech =/= racism. How you came to that conclusion, I am not sure. I think you simply rather insult than debate, and as I said in another thread, the "R" word seems to be the go to ad hominem here when someone is in disagreement. Pretty soon the word "racist" will be so overused and misused that it will lose all meaning.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
