excerpt: Desirable social roles, which were pushed by the female members of human sociums, were consummated with homosexual males, who must have been ‘shamans’ and /or ‘chiefs’. However, this mating may have been desirable not only for their own children, or for themselves to get a desirable social role, but also a defence of the embryos they were carrying in their wombs. As a result, those genes that determine the birth of homosexual individuals must be quite widespread in present-day humans. Only the existence of this social fact explains the impressive percentage of people with homosexual physiology in present-day society, and also that couples with completely heterosexual behavior can give birth to a child with homosexual physiology. The very existence of homosexual individuals must be understood by us, not as a deviation or an aberration, but as heredity.
