Why are Jewish guys so socially inept?

Jew here , so please don’t nail me to the cross (haha).

Have made a point of only dating Jewish guys in my 30s as I’m looking for marriage now & there’s lots of great qualities I find specific to Jewish men , not being heavy drinkers, shyness, the nerdiness & involved parents.

BUT In my experience most of them are suffering with real self-esteem issues, not charming or romantic (at least in the early stages when I feel a date should be trying to make a good impression) & pretty intense jealousy compared to when I’ve dated dudes from mainstream white culture.

micromanaging, controlling of trivial stuff. Like where does this neuroticism come from and how to get them to calm the F down?
