presumptuous.  By way of apology, here's a transporting text from the sixth century Persian philosopher and mystic of Islam, Rumi.  It might make a good e mail in cases like this:

Out beyond ideas of wrongdoing and rightdoing,
there is a field.  I'll meet you there.

When the soul lies down in that grass,
the world is too full to talk about.
Ideas, language, even the phrase each other
doesn't make any sense.

       * Rumi, c. 529

That's what's going on here.  

Racism is nothing more or less than "my tribe good, their tribe bad."  No doubt plenty of rabid racists are also very nice to the people around them, because the people around them are "their tribe."  That however does not make the racism any less evil, nor the tribalism any more viable as an excuse or rationalization.  

What's needed, as the antidote to this, is:

a) On the secular & civic level, reinforcement of the point that we are all humans first, and in America we are all Americans, and if we are Americans then part of our creed is that opening line in the Declaration of Independence that says ALL are created equal.  

b) On the spiritual and religious side, each of the world's religions' core beliefs include the value of respecting others, practicing love and compassion, and so on.  Each (or most anyway) also has various beliefs, seldom at their core, about tribal loyalties and hatreds.  The key here is to keep the focus on love and compassion, which drive out fear, and in doing so, drive out hate.
