I'm not going to worry in the least about naming the guy Greger's talking about. He calls himself James972 and he's a piece of work.
He's also as much a reality of the internet as red light cameras are of the road.
And about as well loved, I might add.

He's a member of something like five different debate forums and he does the same schtick there. And he's almost universally reviled.
