I think that Crabby has a "get Bush" obsession and that he is genuinely surprised when thinks that he has a really good "Bush gotcha" and someone actually disagrees with him.
He has no response to objections because it never occurred to him that he would ever need one.
I think Crabby has figured out that there are some who's chains can be jerked at will - and he delights in so doing. He knows all the right buttons to push to get the pot simmering.
I'm truly amazed that ANYBODY still responds to him!:sleep:
