re: countering
Wasn't trying to literally accuse the 9/11 conspirators of being a Democratic cause. I'm well-aware of the number of conspiracy nuts who are right-wingers. I was just pulling an example out of the air to show how the assumptions look from the other direction.
I will note that those who have raised the subject here have not, to the best of my knowledge, been Republican, and it seems unlikely that this particular conspiracy theory would attract a lot of Bush voters just by the nature of it.
