Should web groups that are considered harmful be removed from the internet?

The trouble here is, who gets to decide what's harmful? I agree on the Pro-ana thing, which has been plaguing Livejournal for years, but there's a hell of a lot of them, and they wouldn't agree. But where do you draw the line? There'd be an equal amount of people, if not more, that would consider Pro-Islam sites 'harmful'. Or Pro-Christian sites, for that matter. Whatever someone believes, there's someone out there who's violently opposed to it. It's been a problem on the Internet for as long as there's been an Internet, or at least since the explosion of the web in 1995. If anyone has quirky or unsocial behaviour patterns, there's going to be a group online which embraces and validates those beliefs. We've got furries, we've got people who think they're vampires or dragons, we've got people who fantasize sexually about having their limbs amputated. I'm not even close to touching the bottom of the barrel when it comes to weirdness, either. I suppose it comes down to the old quote about 'I depise what you say, but defend your right to say it'. None of them, when it comes down to it, are doing anything illegal, other than perhaps self-chlorinating the gene pool a little. None of the sites you mention would have anything in their terms and conditions that would cover such things. Hate crimes, yes, breaking the law, definitely, but otherwise, freedom of speech is pretty universal online. You do right in drawing attention to it, and it's your right to object to it, but facebook also have a point. And given the underlying current of body image and weight loss obsession that plagues society nowadays, I'd say it's really more a symptom of bigger problems than an actual problem in itself.
