This is perfectly revolting, rach, and it saddens me that this sort of ignorance persists. I know it is of little consolation at the moment, but one aphorism which is true is that there are indeed plenty of fish in the sea, ones with more character and brains for a start.
My wife and I are around seventy now. In the early days of our marriage I actually encountered this nonsense directly on one or two occasions from people I had thought better of. A female colleague at work asked me, "What's wrong with a white woman then ?" Another old family friend asked, "Why did YOU have to get a wife from overseas ?" I remained calm in both cases and explained that there is nothing wrong with a white woman and I did not "get" a wife from overseas. For her part, my wife married me against concerted opposition from her family, who did their level best to stop us.
Sorry to hear this type of thing is alive and well. The world is becoming a smaller place and such ideas should have died a natural death ages ago.
