Observe, however the comment section of certain horribly non PC blogs. By and large. they are very smart, and remarkably well informed. Censorship is never necessary, whereas in more politically correct environments, censorship is essential, because when non PC views are spoken, commenters take it upon themselves to silence the heretic by any means necessary, disrupting communication.

If the blog owner posts fairly heretical views, and himself refrains from censoring or intemperately and rudely attacking views in the comments that are even more heretical than his own, then no one in the comments intemperately or rudely attacks any views that anyone expresses in the comments or on the blog.

The blog owner can say that left wing views are held by fools and scoundrels, but because left wing views are high prestige, a left commenter will not be called a fool and a scoundrel. If the blog owner refrains from saying that views more right wing than his own are held by fools and scoundrels, then commenters with views more right wing than his own will not be called fools and scoundrels in the comments.

Because right wing views are low prestige, it requires only the slightest encouragement from the blog owner to produce a dog fight in the comments, should someone further right than the blog owner comment, but not so easy to produce a dog fight when someone lefter than the blog owner comments.
