Disavow Trumps racism? What racism? 
Are you also in favor of ending abortion?  ...Jesus wasn't pro choice. 
How about ending homosexual marriage? ... Jesus was no fan of sodomy.
Trump's morals run much much deeper and wider than anyone the democrats put up against him and lord knows that Bernie da Bomber isn't Christ-like in the least. I think the easiest way for you to see how wrong your thinking is about Trump is to start doing your own critical thinking and drawing your own conclusions. Most of the remarks the press has a attributed to Trump are either complete fabrications, were true, were taken out of context and all over reacted to.
