But the complaint here is that what’s happening isn’t actually freedom, but it’s complete opposite. Threats, harassment, and abuse aren’t intended to further debate but to silence it. This “caustic freedom” of anonymous abuse you speak of is completely corrosive to free speech. Finding the right ways to minimize it would be a net gain for open discussion on the internet. Certainly there is always the risk of suppressing legitimate dissent, but a forum full of trollies is vastly more effective at doing that already.
