It's pretty appalling stuff, Africans as savages, advocating eugenics, as well as comparatively innocuous things like calling other contributors evil, and being a bit too eager to express hatred for entire nations, etc...  I personally think ET is walking on thin ice by tolerating some of this stuff, though I understand the desire to err on that end.  

Just because a somewhat intellectual argument can be made for something (though I think there is a bit too much of the visceral in these comments to preserve any intellectual integrity they may have) does not mean ET should be obligated to provide a platform for them arguments.  And the rest are just sophmoric attempts to ignite flame wars.  Kudos for those who don't take the bait.

I don't know just where I stand on banning.  It hasn't set well with me in the past. Doesn't ET have a mechanism like DKos where if you are troll-rated enough times you can no longer comment?
