Discourse is most productive near the very limits of civility.
It's Too Scary, So It Can't Be True
When you cut to the chase, the push back to arguments from realism you get from most apologetics boil down to this: "It's too scary, so it can't be true". Doesn't mater whether it's morality, evolution, or any of a thousand other topics.
Essentially there aren't any. If at some time some vitriolic troll happens to start annoying me in my own house, then that may change. But before that can happen, more than 5 people will have to actually visit the site so I'm not too worried about that. Sorry to add the verification step, but unless spammers are going to pay me - no free lunches!
