I told you it's a weird idea. In my mind I think that the "sins of the father" (meaning, in this case, the sins of the white colonialists who made the slave trade a part of our culture) will take many years, many generations to overcome. So while it's easy for many of us to say, "get over it, blacks have alot more opportunity now," the remnants and the repercussions of slavery are still alive in the descendents of the slaves, and we, as a society, still suffer from those consequences.
I'm happy that you coexist happily in SC as a color-blind community, but as a country, the wounds are not healed. You see that in the disparities in the experience of blacks vs. whites today. Even
Megyn Kelly gave Bill O'Reilly a talking-to about this.
OK, maybe my math is wrong, but a generation is typically defined as around 30 years, so 7 generations is 210 years. And I don't take this literally, like in 2075 everyone will wake up all healed and happy. But I think time has to pass, and I think that the response to the event in Ferguson is still tied to how blacks were treated in 1865, not even consciously, but subconsciously, almost at a cellular level.
In the book "In the Realm of Hungry Ghosts" by Gabor Mate (which is a wonderful book about addiction), he talks about how children who are in utero when their mothers are going through a stressful time have that stress imprinted in their DNA. They haven't felt stress at all--but it's transferred to them, and the likelihood of them growing up to be addicts is more likely than those whose mothers were stress-free. So I think it's a similar concept, and also similar to the Jungian concept of the collective consciousness. Some things are transferred through time, through "ether," through cells.. and they hang around, until we transform the experiences and feelings and change things for future generations.
