Ask any liv what the % of gays to straights is and they will guess 10-20 % instead of the actual 4%. This is because tv is pushing an agenda and there is at least one gay in every show. This skews the numbers and gives an appearance of normality instead of fringe behavior.
A month or 2 back, the CDC IRRC showed a long term study showing the figure at 1.5%.
Same thing with blacks. Most people will tell you somewhere in the 40% range instead of the 13% or so.
Actually, a government study said 1.6% of the USA population is homosexual. and 0.7% is bisexual.
