John Podhoretz manages it:

Rall is basically little more than pus in human form.

well that's a real contribution to civil discourse.

Why do bloggers and columnists with large audiences even mention Rall? Of course he's an odious person, but his M.O. is that of an Internet troll. Public condemnation by reasonable people is probably good for business in the leftist fever swamps where he works. It might be better to try to avoid giving him additional publicity.
