A few points:
The standard explanation is, and should be the default explanation: given that we know that there were planes that crashed into the towers, we know that OBL had "declared war on" and attacked the US previously, that the attackers had previous ties to Al-Qaeda, among their other extremely well known and studied background info, etc, we have more than enough info to establish that there was in fact a successful Al-Qaeda plot to attack the WTC, in essentially the known manner.
So the conspiracy theorists are starting with exceedingly weak priors for their case; they also have no persuasive/effective evidence in their case's favor. I don't really feel any need to list every possible argument against the standard case and their flaws, but see eg here or here.

Now, I have definitely noticed I'm confused here. While I hold the opinion that the towers went down because of the planes/fires (i.e. the standard explanation) I have difficulty seeing how the falsity of controlled demolition is the slam-dunk folks seem to think it is. Could somebody walk me through this?
