Homosexuality was only the "norm", in Africa and to a degree among Amerindians.

Amerindian mothers, would often raise their most attractive son like a girl, then sell him off to an older homosexual.

Blacks in their native, African state(without outside influence), are alot like the Bonobo chimps, in terms of display of social sexual practices. So you see everything:

Homosexuality, bisexuality, crossdressing, women acting like men(and dominating men as an alpha "male").

It is ironic that modern African nations, call homosexuality "foreign imperialism", when Africa was always the most sodomite happy continent prior to European conquest of Africa.
