To believe this monumental piece of nonsense you would have to believe a conspiracy so HUGE and far reaching as as close to impossible as is possible. Have you any idea the thousands of people involved in the investigation of the tragedy? No way can that many people keep a secret such as you seem to be implying was done.
As for the windows blowing out. A fire inside a house or other building without a collapse can blow windows out just as extreme heat without a fire can blow the windows out of a closed up car on an extremely hot day. Plus as the buildings compressed (collapsed) the downward force caused the windows to blow outward as the atmosphere inside the bldgs was forced outward by pressure.
You cannot name any “conspiracy theory” coming from the right, completely devoid of any kind of facts and so absolutely ridiculous only a complete loon would believe it, with these kind of numbers or anywhere near 35% believe it.
Your entire premise that both sides have equal share of nuts is completely flawed.
