popa, does your mother know you post here?
did she laugh when you asked her this question (as we did when we read it)?
basically, you’re saying that since women are not obligated in those mitzvos you listed they are not jewish, i.e., jewishness is defined by the obligation to do those particular mitzvos.
well, for one thing, aren’t the ten commandments pretty important mitzvos? not one of them is gender specific.
second, aren’t women obligated in three specific mitzvos? are you, that is, men, not jewish because you don’t have to take challah, light candles, or keep thm as women are obligated to? (true, you can take challah and light candles if there’s no woman around to do it, but we can make kiddush etc if there is no man around, too.)
now, i have a different question: you know that joke about the guy going to three different rabbis because he wants to be a cohen, and the orthodox and conservative rabbis tell him he can’t become one, and finally the reform rabbi says no problem, just why do you want to become a cohen? and he says because my father was one, and my grandfather was, etc. hahaha, what an ignoramus, right?
well, what if his father married out? true, he should be a cohen because his father is a cohen and that follows the father. but jewishness follows the mother and if he’s not jewish, he can’t be a cohen. so there goes the joke.
what if he converts back? he can become jewish, but can he become a cohen retroactively?
