We have lived through fear all our lives, and when you have gone through a whole lot of fear, sometimes all you can do is resist the fear, and resistance comes in the form of courage.
We do not accept the Western way of thinking that there are two ways of life. At the same time, the police (here) are not chasing gays. In Africa, sexuality is something very private, even for heterosexuals. Heterosexuals are not parading! But gays want to behave like exhibitionists.
