The idea that African homosexuality was a colonial import is a myth
Africa has 54 countries and more than a billion people. One of the most ridiculous myths about it is that homosexuality did not exist in the continent until white men imported it. Robert Mugabe is one such propagator, calling homosexuality “un-African” and a “white disease”.

As for what Pepe stated, she is right; you can blame others as much as you want, but it solves nothing. The past ignorance from the Brits that lead to anti-gay legislation in Africa and some Christian missionaries advocating for persecution of homosexuals does not excuse other for part-taking in the same behavior. There has been a lot of distortion in the continent of Africa and in the Eastern world, and they have to break the mental chains from the past. Finding their roots, their history absent from the manipulation of others.
