It appears that they are convinced that the Bush administration was behind the 9-11 attacks. They cite various "evidence" such as WTC Building #7 collapsing, Bush's brother being involved in WTC security, etc.
Now, I am as anti Repugnikkkan as anyone, but, to think that the gang of fuck-ups that were running the country for (at that point) less than 9 months could have devised and executed anything as complex as the murders of that awful event is a bit delusional. This ain't the movies, and would the government be able to have kept it quiet? Come on now.
Sure, the USA has been complicit in starting wars before. The Spanish American War ("Remember The Maine" - blown up by pro US war factions), WW1 (The Lusitania carrying munitions) and Viet Nam (which was a tie!) were all shady. However, to think that elected officials would be insane and callous enough to have planned out 9-11 (including the Pentagon bombings) is sheer lunacy. Or something.
These left leaning folks make the Tea Party look sane.
