This is true, but their gayness is usually because they are gay while with sisters it's more of a faze or being influenced. For example, I have a cuisine who was gay. Still, it was just one of her many fazes, that took her from dating thugs, Jamaicans, and white guys to women like she was searching for happiness as if it were a treasure hunt as opposed to something you create and build with meaningful relationships.
That is the thing about many blacks here in this country, without our own culture and religion we are forced to mimic the culture of the white man, and if they feel empty with that shit, we feel like we are missing something that was never there to begin with. So we go from one phase to the next, searching and seeking while the answer for happiness has always been within us, the black man and the black woman creating black families. While this may not be as glorious as the lies told to us from the lies in the images from mass media and the commercials.
Yet, nothing can beat the joy of watching the reflection of yourself grow up to be greater than the sum of the two parts that created it. This is the true meaning of life that they stole from us and replaced with greed, perverted lust, selfishness, and the notion that one day around some corner a savior will come to us making all our dreams come true.
We have been sold a lie but will defend it to the death because in our minds the lie looks so much better than reality!
So yes there are gays from every race, the difference we tend to do it to escape who we are by following what we have been convinced happiness is.
