There is a Rabbi in our community whose wife is Ashkenaz. Their children married into many of our community Rabbis’ families. In fact they have many grandchildren(Kein Yirbu) with Ashkenaz first names with an obvious sephardic last name. So please, do not assume all Syrians don’t mingle with Ashkenazim. If my children were redt a shidduch, with someone Askenaz, I would have no issue with it. And I make a point to tell my children that. So long as the person is a Mentch, and a Jew. Go for it.
Cherrybim,If anyones attitude is divisive, it is your own. please look at things with an Ayin Tov.
