rebdoniel: In the world of shidduchim a young man like you would indeed be most welcome in modern orthodox circles.
I have a Sephardi husband of mixed Iraqi, Temani and Morrocan background ( a very Israeli phenomenon) and our children who proudly celebrate my husband’s traditions have found the modern orthodox world not just welcoming, but respectful and accomodating. My sons have married Ashkenazi girls who are happy to take on Sephardi customs, just as I did many years ago. My daughters have spouses who were happy to share our traditions, even holding hennas and doing their best to learn traditional songs!
There are many shades of orthodox Jews, from Modern Orthodox to Haredi, see them at my Shabbat table as my family has moved in different ways and most people behave with ahava Yisrael, those that don’t simply don’t count.
I understand why some communities are protective regarding giyurim, but see no need for a young sincere man like you to feel awkward. Keep looking till you find a welcoming community, you are certainly in a big city with lots of places to choose from! A boy like you has lots to offer especially for shidduchim, sincerity and belief that spur one to act and change one’s life are special qualities that will attract a sincere match.
I speak as a mother of daughters!
