Well anyway Racist sounds stronger than xenophobia. 'ist and phobia are different. Phobia usually means that you can't help it. But in this case we could link both to Roots. Nigeria, and America are both roots. So a better word that links both together is Rootist.

You are being Rootist.

Or think of a better word that links both together, because I feel that both cases are linked somehow.
