I am a Yekke who just found out that my family is actually Sephardic. My wife’s family is Satmar but she follows Breslov philosophy. She follows what I follow when it comes to Minhag and yes, I asked if I needed to”revert” to my Sephardic roots and was told no by two big poskim. So there you go…
Here’s the thing. My best friends are Gerim who follow Lubavitch and an Ashkenazi who was mekareiv Eidat HaMizrach. Who cares? We are all Jews. Wives follow their husbands and everyone is happy.
