I want to know the answer to the following question:
What were the calculations of this myth?
All the background I'm provided with is that "For this reason, in the 1970s Bruce Voeller, the chair of the National Gay and Lesbian Task Force perpetuated a common myth that the prevalence of homosexuality is 10% for the whole population by averaging a 13% number for men and a 7% number for women.". Is that enough to answer the question?
