The conclusion was my extrapolation based on the assumption that unfettered hostility is generally a bad thing. It depends on the mission of the forum, I suppose. A political forum that wants to foster a thoughtful exchange of ideas where everyone's voice will be heard needs moderation. A political forum that is fine with name-calling might also grow, albeit with a different cast of members.
