I fail to see how "true information should be promoted, false information should be suppressed" is a controversial statement. I'm not talking about opinions here, just cold hard facts. If someone wandered into one of my communities and actively encouraged people to mix bleach and ammonia, and my users were falling for it, you bet your ass that person would get banned for violating my rules, and I would be making sticky posts warning about the dangers of what that user was promoting.
The idea that I can't regulate what goes on in my community because "free speech" is absurd. The same goes for Twitter and YouTube.
