Kk - nope, I grew up in the suburbs of Boston, where the most exotic folks we ever saw were - gasp - Protestants.
Then when I was 12 we moved to a suburb of Pittsburgh which was less Catholic but not any more Jewish. I did, however, marry two Jewish men (not at the same time, of course) and therefore have learned a lot about the rules/laws/traditions.
If I had to clean the house with a feather to make sure no chametz was hiding anywhere before Passover - well, let's just say I might have hopped a freight train long ago.
Jules - high five! I did the same, more or less. My son was allowed to have his room as neat or messy as he wanted and I tried to butt out and ignore anything I didn't like. I taught him to "swish and swipe" his bathroom every day (see Flylady) and spray down his shower walls with a daily shower spray and then I just left him to it.
It helped that, as a teen, he had the whole second floor of our cape cod house to himself, so I never really had to confront whatever was happening up there.
