R. Paul supporters I have spoken to face to face also believe the planes that went into the WTC were remote control and other wacko beliefs.

Something about him definitely appeals to the mentally unbalanced, much like the other L Ron.
You can’t manage defensible positions, so you resort to petty smears. Ad hominem is a logical fallacy.
