That is about 2X’s higher than any credible study ever put the instance of homosexuality. It is believed to be around 1.7% of the over all population. That includes children and the elderly who are not engaging in regular, consenting, sexual activity. IOW 1.7% is even too high.
Studies show that most young people believe that homosexuals encompass over 25% of the population and given the constant gay drum beat, who can blame them?
I can blame them for accepting what's told to them by the educational establishment and the media and not wanting to find out the truth for themselves.
