I've suspected that Bigsby is a paid plant on this and other forums. He (always) takes the administration/government/establishment side of any issue and argues using scorn and trying to discredit rather than disprove. You can't convert someone who's being paid to cast doubt on everything.
I ignore Bigsby as he never has anything real to add to the debate.
What difference does 911 make anymore? Even if a group within our government did intentionally destroy all of the WTC buildings what can an individual do?
