I think he means the opposite, which is that he fits the "white christian male" and feels that there is hostility towards towards people who fit the "white christian male" bill.
To the contrary, I am usually assumed to be middle eastern (egyptian, oddly enough, although it may not be that surprising considering the hellenistic period and where my relatives are from) and despite being Christian, I am not one of the accepted mainstream forms of Christianity in the US, so I face double prejudice, on the one side from those who think Christianity is the cause of all the worlds problems, on the other side from other Evangelical types who think we are idol worshipping heretics. It is only when I correct people, that I get the "oh" reply, usually in disappointment that now I don't qualify for one of their acceptable groups of people who experienced prejudice or a lack of acceptance.
