Jimmy, glad to see folks are becoming aware of this and are willing to discuss it from an unbiased learning perspective.  You are spot on with your comment about owning land.  There are many obstacles facing anyone wanting to start farming, one of which is owning land.  Less than 2% of farmers in the US are black.  A majority of them are in the south and have small farms.  When the Civil War was over freed slaves, most of whom had worked on the farms there, were promised "40 acres and a mule" by our Federal government.  Never happened.  When you have few, if any, possessions and no one willing to help you establish an operation from a capital perspective, it had to be pretty discouraging.  In addition, even though they were free, that didn't change the society they lived in.  Discrimination and racism were still present, much as it is today, although it exists now a more subtle way.  For example, if you take a position in support of any black cause, then you are labeled a liberal by many in the ag community.  Not good.
That being said, a young person on here asks how do I get started farming?  Without going into detail you know the typical answers.  Look at those answers from the perspective if you were a young black.  If a black, who had the necessary experience, came to you wanting to work for you would their race be an issue for you?  Would employing them be viewed as a positive, or at best indifference, other farmers in your community?  What if your farm were for sale and a black had the money and wanted to buy it?  Would they be welcomed in the community or would the old adage"well there goes the neighborhood" prevail?  
The first step to solving a problem is recognizing and admitting there is a problem.  This requires an open mind and a willingness to listen and learn.  It is hard to do, it was for me.
