Actually, it's not acceptance. It's a willingness to give the benefit of a doubt.
There are those who can twist facts to fit any purpose, just as some have done to make it look like Bush had some involvement in the plot to fly planes into crowded buildings so he could act like Mighty Mouse -- and Republicans can stay in power.
Do I think anyone in congress, Clinton or Bush administrations would purposely, knowingly, or otherwise allow the carnage that happened on 9/11 to occur? No. Do you?
Being a whittless twit is one thing, but being convinced something bad is going to happen and not doing something about it is another.
Personally, I think DC is full of whittless twits and unfortunately, we suffer the whole load of unintended consequences when the twits are making the choices.
