Trump is a racist. This isn't up for debate. There's no discussion to be had. It is a factual statement.
Of course it's up for debate. He denies he's a racist and has condemned the KKK and Nazis and other hate groups. He obviously didn't pledge to do any racist acts or support racist laws and policies as president, did he? If you say "yes", which? But he has pledged to clean up violent crime and provide more jobs in black communities, for example.
Please define what you mean by racist and then give me, say, 5 specific examples.
The border wall? This can obviously be supported by people who simply support closed and well secured borders for the safety of Americas citizens by restricting the flow of illegal guns, crime, drugs, gangs, terrorists, etc. Or the wall could be supported for economic concerns as millions of unskilled laborers with poor education flood the welfare system. Agree with it or not, a border wall is not inherently racist.
The ban on immigration from Islamic nations that are hotbeds of terrorism? First Islam is an ideology and religion, not a race, so it obviously isn't a race issue. Most Muslims today are non-Arab, I believe. Anyway, such a law could obviously be enacted with the protection of the American people in mind, in an effort to thwart Islamic terrorists, who, yes, often do come from these nations. Agree with it or not, a travel ban from key terrorist Islamic nations is not inherently racist.
