. . . there will be a lot of racists upset if it is a white man. . . .
I think that it is perhaps too simplistic here to talk about "racists", "white supremacists" and even xenophobes. I think that what we are talking about here is people who are resistant to / frightened of change.
They feel quite comfortable knowing that the nearest they will come to anyone or anything different is taking a chance by going to an Indian or Chinese restaurant but if someone comes along who looks a bit different from them, speaks differently, has a different outlook on life, has different values or God forbid - speaks a language that they can't understand, they are quite simply terrified.
Despite the words of John Donne and Paul Simon, there are people who do believe that they are in fact islands, untroubled by change and they want to keep it that way.
