The latest Gallup poll suggests that Americans think that nearly 25% of the population is LGBT. That's more than Jews, or even Catholics. Those with lower levels of education think the rate is even higher.
Probably about 3-5% of the population identifies as gay, and probably 10-15% have had some homosexual experiences.
To some extent, this may explain the increasing hysteria of NOM and the anti-gay crowd. I wish they would just get over it and realize we are about as threatening as a redhead.
THen again, there have been attacks on gingers, too.
