David Duke is a high-profile leader of the white supremacy/white nationalist movement.  His endorsement of Mr. Trump's comments and his appreciation of Mr. Trump's positive stance toward those groups is hardly "unimportant".  Take a few minutes and visit some of those white supremacist/white nationalist sites and note how appreciative they are of Mr. Trump and his comments.  BTW:  Explain to me, if you will, how "very fine people" march in and, and thereby support,m a demonstration sponsored and led by white supremacists. IMO, being a racist and supporter of racism excludes one from being a "very fine" person.  You might define that as "intolerant"......To openly oppose the evils of racism..which is, of course, the epitome of intolerance...does not, IMO, constitute intolerance.  To me it constitutes human decency.  What do you think?  Gary Crum
