There are degrees of things. It's true that many people have some beliefs that are unconventional, irrational, or even radical, but many also realise at least to some level. There are many religious people who will admit they can't prove any of it. Similarly, in general people tend to overestimate how much people agree with them, but you can overestimate by a little or by a whole lot. It's my general observation that many conspiracy theorists are far more sure of "the truth" as they see it than the average person. This is also why so many keep banging on about it in any venue, whether appropriate or not.
