They rig these things all the time ,I'd love to see what survey or questions they asked the groups , and how the groups were chosen .

They could take 1000 college students , who are inclined to say they are gay / lesbian because they wanna look cool, and express that as a fraction of the population.

There was a study in a college where 40% of the college said claimed to have been sexually assaulted and then that study (obviously a load of shite) was used by various NGOs to lobby for x or y .
