No, I don't consider what a person says on their own blogs trolling. I think that people can direct the course of a conversation anywhere they want it to go on their own blog.
I'll be honest with you Doc, you guys call him a lot of names, and on HIS blog. You've all said pretty vile things about him and I don't recall him deleting a single instance or blacklisting any of you. To me that counts for something. Granted, you are also serving to bump his blogs and keep them in view, but he's not twisting your arm to do it.
Just be honest, and go back and look at the Col's average blog and see how many times you guys call names and sleight him without commenting on the meat of the article. I think you'll find that in terms of trolling, the righties dealing with him have no room to talk.
I'm guilty of it as well from time to time, I admit it, and readily accept trolling points for when I am. You definately won't catch me trolling him for just giving back what is handed him.
