This topic question doesn’t make sense.
Ashkanazi, sephardi, chabad — same ocean, different boat.
I know a nearby place that has all three shules in one building.
I have seen charedi ashkanazis impressed with some chassidic rebbe’s Torah discourses they read.
The ashkanazi vs sephardi and ashkanazi vs chabad is old cobweb from our parent’s and grandparent’s days. Kids today don’t give a garden of fig trees what you are.
I know plenty of sephardi/ashkanazi couples. Chabad/ger tzedek couples. etc
It traditionally goes by the husband – women only do a fraction of the requirements men do. What does it matter if they have a sephardi accent from india if their husband and kids went to a chabad school?
And finally, it doesn’t matter what you are. If both parents are sephardi and the only proper religious school is a chabad one —> your children will grow up chabad. It’s what school they go to, what fridnds they hang out with.
