And if you have civil debates on Facebook, your social circle is extraordinarily strange. Also, Facebook is moderated by the person whose wall you are posting on. I've seen effective moderation in this way. If you have friends that value good discourse norms, and you shitpost in the discussion around their posts, they can and will delete your shit and tell you to knock it off.
