"Black men are primarily responsible for that." This part of your statement is true. This country would not exist were it not for millions of black slaves. The colonies from Maryland south would never have joined the "Revolution" without protections for race based slavery. We would be more like Canada without race based slavery.  In 1860, 80% of the wealth of the nation was from slaves, slave labor, and the products that labor produced. The violence today is a product of our history. The rest of your statement is just fake news.
