You rarely see non Jewish (Christian) men marry Jewish women but often see Jewish men marry non Jewish women. And believe me, it seems almost 100% of the time the kids will be raised Jewish even if the spouse never practiced the religion for any amount of time.
One famous exception: Brian Wilson of the Beach Boy’s first wife was Jewish, and both his daughters consider themselves “Jewish.”
You’re right but I do know one Catholic guy who married a local Orthodox Jewish gal and they are quite happy.
They did suffer the tragedy of losing a 9 year old son to Cystic Fibrosis....gut wrenching.
