At least half of Trump's supporters are racist so I am not sure what is so controversial about this statement. About half of Republicans supported him in the primary when they had other choices. I can understand there are many Republicans who can't support Clinton but they are in the other category. At least half of the people supporting Trump are racists who just want their country back from the non-whites. Great Americans, they are. Anyone who isn't white isn't really American.
And you know this how?
I think the better word is bigot. The people who supported Trump in the primaries are bigots, plain and simple. People who support Trump's candidacy not because they hate Hillary because they like what he says, are bigots.
You seem to think that you are not a bigot. I am here to tell you that you are. You have in the past said that some people are not fit to be immigrants to America. I questioned you on it but you never responded back. America's history is defined by immigration here by Europeans. So why exactly can people not of European background not immigrate here? I can understand opposing illegal immigration as well as supporting limits on the level of immigration. But when you imply that certain people can't immigrate here because of how they look, or the faith that they practice, you are being a bigot. And half of Trump's supporters are most certainly bigots.
