Slavery and Black Churches

I have always wondered why black people cannot just get over slavery. Seriously, it has been years since it happened and it is ridiculous to keep bringing it up. Now as annoying as that is I hate the churches who dwell on like it was completely the white man's fault and that they should be reprimanded for what happened.
First off, it was not as if the white man surprise attacked Africa and stole the people. They went there civilly and BOUGHT the people from the kings of the nation. Yes, bought. The black man sold each other out. Now people could say, "Oh the kings were unaware of this." But GET REAL. The kings knew exactly what was going on. They may not have known what would happen to the people when they arrived in America, but even if they did NOT they are still fully held accountable for their actions.
In addition, I do not like how black churches rise up and say the black man needs restitution from the white man. Let's get very real again. Jesus Christ was beaten to a bloody pulp. So distorted and torn that he did not even take on a human form. He literally had his facial hair ripped out, probably taking a chunk or flesh from his face. A crown of thorns was impressed upon his head also tearing the flesh on his head and touching his skull. After all, of that he was forced to carry a cross up a hill, while being beaten along the way. Until he had fallen and someone had to help him. After carrying his OWN cross. He willingly lay down and had his hands and feet nailed to a cross. As he hung there, he had to press himself up in order to breath-because when you die on a cross it is because of asphyxiation. So not only was he pushing up his own weight. He was pushing up the weight and the sin of ALL mankind-past, present, and future-on him. And never one time did he curse a single soul. Never one time did he say you will be damned for what you have done to me. Never one time did he even wish any bad thing against them. All he said was, "Father forgive them, they don't know what they are doing."
So how dare you carry a grudge so long and put God's name on that! How dare you forget the same God you serve is the God who went through torture worse than slavery and overcome for both you and white people. How dare you!
I am not stating that it needs to be forgotten I am just stating that it should be reverenced and not held as a judgement.
