Mr Smith writes "I suggest every racist be given a DNA test and shown where in the chain of humanity he is connected to all other humans."  Of course that test would reflect commonality with AfricanAmericans as well as every other human being on the planet.  If you compare any two racial or ethnic groups you will find far, far more commonality than difference in physical make-up.  Racism and ethnic bias are learned and, somehow, we all need to work together to address and hopefully erase those racist and ethnic biased concepts.  Unfortunately, IMO, Mr. Trump's presidency has had exactly the opposite impact.  That's truly sad.  Gary Crum
