I don't really understand this sentiment. If we admit that we all hold beliefs that could be wrong, isn't the ultimate conclusion radical freedom? The radical freedom of the internet isn't a result of a set of beliefs, it's the result of evicting belief and allowing all ideas to stand on their own merit.

I think you're wrong here. The world is becoming an exponentially more peaceful and tolerant place in my experience. There is still a vocal minority which gets attention thanks to the open platform, but the overall result of this openness seems to be growing disdain for beliefs which we now know are founded in hate, not logic or science. Do you really feel that the world is in a worse place than it was in the 70's or even in 2010? In what ways?

Genuine question, what percentage of 4chan do you believe is racist? Do you feel that racist memes genuinely come from a place of racism? What large anonymous groups do you believe consist of genuine racists? Do you consider me a racist if I make the statement, "more crime in America is committed by people with dark skin, relatively", even if I make no attempt to suggest a correlation or reason for this statistic?
