WTC7 in Freefall: No Longer Controversial

I've noticed a lot of rhetoric calling those who question 9/11 idiots, retards, lunatics, #$!@ morons, dingbats, etc...etc...

This would imply that there is a much broader window of knowledge out there that many seem to have missed altogether when analyzing at this event.

If this is the case, can anyone please explain to me how the following is possible? Thanks!

NIST initially denied that WTC7 fell at freefall. In their final report in Nov 2008
they reversed themselves and admitted freefall, but denied its significance.
