I can't comment for the States as I live in Europe... but 99% of the big vocal trump supporters at this side of the ocean are racist and xenophobic like there is no tomorrow. In this country the only political trump supporters are the ones that has historic ties with the nazi's. That the most vocal European Trump supporters at political sides are in most case from extreme right political parties is also very telling.
So yeah it could be that you aren't racist or xenophobic but his message also really speaks to racist all over the world and that is fact.
