Trump was a lifelong Democrat so that would meet one qualification for a racist.  Democrats are the Party of Slavery and Jim Crow Laws which gave us legalized second-class citizens. The KKK was formed by former white supremacist military officers defeated by Lincoln's army.  They were all Democrats who hated the Republican President.  Their nice statues are being pulled down by other Democrats.  
American Nazis hate just about everyone; Jews, Blacks, Catholics, Mexicans... and more.  I won't put those morons on the Democrats even though Democrats put them on Republicans everyday.
