Biased doesn't require being unfair.That said, how does TOL suffer if someone isn't as biased, is by definition more fair? Who is harmed by it?
One of the few things I don't like about TOL is found in the whole bias business, politically applied. If the bias is a Christian sensibility I see it. There has to be a standard of conduct. A right wing bias just invites contempt for the rule and smacks of tariffs, that is a protection for a thing that can't stand on its own.
I don't happen to believe conservative philosophy requires extra protection and that's all it can amount to.
TOL is biased, and is also one of the fairest sites around.
But let's be clear ........
TOL doesn't exist to be a utopia of "fairness".
Knight could ban someone for any reason whatsoever. In fact, he could ban someone for no reason at all.
And he doesn't owe anyone an explanation for why he did so.
