I don’t like to accuse people of racism. That word is used far too often, unjustly, to smear good men and women. It has been thrown at House Speaker Paul Ryan, Sen. John McCain, former Gov. Mitt Romney, and other decent conservatives. It has been attributed to anyone who defends law enforcement or opposes a government program. When everyone on the right is a white nationalist or white supremacist, these terms lose their meaning. But Donald Trump is a racist.
