As evidence of the “innateness” of homosexual attraction, LGBT* activists often refer to research neuroscientist Simon LeVay from 1991, in which he allegedly discovered that the hypothalamus of "homosexual" men is the same size as that of women, which supposedly makes them homosexual. What did LeVey actually discover? What he didn’t find unequivocally was the connection between brain structure and sexual tendencies.

One of the slogans of the "LGBT*" movement is the claim that the proportion of people with homosexual attraction is supposedly 10% - that is, every tenth. In reality, according to large-scale modern studies conducted in the United States and the European Union (that is, in countries where homosexuality has comprehensive support and protection from the state apparatus), the proportion of people identifying themselves as homosexuals varies from <1% to a maximum of 3%.
