It forces you to reject, possibly without cause, the rationality of experts who dissent from this consensus

If experts disagree, then there simply isn't a strong consensus.

Personally, I am not a professional demolitionist, but I have yet to see any argument that WTC7 was brought down in a controlled demolition which reflected a technical understanding of the subject greater than, or even equal to, my own. If I did find such an argument, it would change my opinion on the subject considerably... although that would only be the first of many hurdles to overcome before I would be willing to believe that the full "inside job" hypothesis had been proven beyond any reasonable doubt.
