Yes, we are to judge Nazis. We fought a war over it. Google is different. They provide a service and should tend towards neutrality. Reddit and Facebook are not a service, they are a communication platform more like a TV network. Google is like a phone book. So yes, if Reddit and Facebook don't want to be overrun by trolls they have to put limits in place. This is not censorship anymore than it's censorship for ABC not to pick up a pilot for a TV show. It's their platform and so you play by their rules. Unlimited free speech is not a guarantee and the people who think it is either don't understand it or are abusing it on purpose to rally to the cause of posting pictures of dead babies and pictures of women's underpants taken on subways. These sites need to enforce decency like any other media company that wasn't founded on a misunderstanding of the libertarian ideals of the early internet that were about making software available so IBM didn't own every damn thing.
