Well, you've been very sheltered in your travels, then. That may have been true in 1960, but with the destruction of many black families by welfare and drugs, beginning in the 1970's, a whole new subculture began. There are women selling their five year old daughters for crack cocaine. This started years ago. Those children are grown now, and have had children. Many of these children have never been exposed to anything other than drugs, prostitution and gang wars. I've seen them six and seven years old, roaming the streets at three and four in the morning. Nobody raises them, and nobody cares where they are, what they're doing, or who they're doing it with. These are the kids that sat in dirty diapers while their mothers shot up and turned tricks in the same room with them.
I know you are sincere in your beliefs, but you're sincerely wrong.
