I don't really care what anyone chooses to believe as long as it doesn't negatively affect me or they try to ram it down my throat.
And for the record, I think the investigation after 9/11 was far from thorough or necessarily accurate and there are some strange things about it. Like how so many people were magically able to make cell phone calls from the airplanes, but Occam's razor and Hanlon's razor both apply IMO. Don't attribute to malice what can be easily explained by stupidity. And the simplest explanation is usually the right one.
