Is Donald Trump a bigot and racist?

News: People are starting to get a negative vibe from Donald Trump, is he right for president of America? Is he too strong on his opinions? Washington Post seems to say so.
Some will think this an outrageous label to apply to the frontrunner for a major party’s presidential nomination. Ordinarily, I would agree that name-calling is part of what’s wrong with our politics.
