You 'black folks' will not get paid for all that labor prior to 1865.

You didn't perform that labor.  

Those who did have been dead for over 150 years.

You aren't going to get 40 acres and a mule, either.

I had two great uncles who fought in that particular war.  One fought on one side, one the other. 

They were from Missouri and neither gave a damn about slavery one way or another.  

Both survived.  And never spoke about the war afterwards. 

 Our family refuses to hate either of them for trying (in effect) to kill each other over such strongly held personal beliefs.  

 Our family got over the hate.  It is unfortunate that you cannot.
