The scene with Ron Paul was most certainly not done with willing participation. Otherwise, most of the scenes seem to be the product of social engineering. Example:
The bar scene. Apparently they advertised a cage wrestling match to load the place with angry straight guys... then they were practically giving the beer away... then, once people were absolutely blitzed they handed out free t-shirts that had anti-homosexual slogans. If this wasn't enough the promoters then tell a drunken mob that they won't be seeing the promised match... THEN they film the portion for the film.
The end result isn't so much about the individual sober feelings of the people in the bar, as it is about the social engineering applied to make it look just how they wanted.
