I married a Baal Teshuva. Many folks of my parents’ generation did not want their children who were FFB to date someone whose parents were not frum. Did that make them “frum”-ists (I can’t think of another word to describe religious chauvinists)? I don’t believe so. My parents indeed would have preferred for me to marry a boy from a frum family, machetonim with whom they would have potentially (though it is not always the case even with a frum other side)had something in common other than the children. Fortunately they saw what I SAW, when they met my husband to be, who was one of the kindest and most derech-eretzdig people I have ever known. He was a great son to both his parents and mine and my parents loved him dearly and he, them.
That is not always the case, and not every parent can adapt as easily. While Politically Correct people will say the skin color/race should not matter (and it shouldn’t), it somehow DOES to many people, and they should not be castigated for their feelings. Just as we would want them tp understand how the OP feels, so too should the OP and others who have supported his position understand how THEY feel. Neither side is wrong for their feelings IN THIS CASE. What may be wrong is how people act and react to their feelings. I wish there were an easy and ready solution.
