One primary value of America is that one never accuses another of wrongdoing,  unless their is sufficient proof to support the accusation. Otherwise the person making the accusation is committing slander. 

What do you have to offer in the way of proof, let say to the level of having a jury in a court of law decide on the question,  that TRUMP is a racist. You might also want to define your terms. 

Xenophobia is a fear of strangers. Mr. TRUMP has traveled all over the world. He has lived in American cities  of great diversity. He has hired thousands of people, of diverse characteristics, to work for him.  And throughout his life he has treated people equally and with respect no matter what, in terms of race, religion, sexual orientation, or gender,  etc... There is no pattern in his past to suggest otherwise. Again what would a court of law say.  

So I would ask you to uphold American values of presumptive innocence and refraining from spreading gossip.
