Zahavasdad: A ‘marriage’ between a Jew and a goy is not considered to be halachically valid anyway, so converting the non-Jewish spouse is always ‘for the sake of marriage’. It is straight up halacha that we can’t accomodate these cases, one of the reasons is that it is rewarding the intermarried Jew for his/her wrongdoing.
”Kicking people out is not going to work”
It works for the Syrians, intermarriage is virtually nonexistent in their community B”H. We are better off without the people who will still intermarry after all the warnings and education against intermarriage, seeing the harm it has done to Klal Yisroel. Those with Jewish mothers and non-Jewish fathers are Jews and we definitely should be mekareiv them, yet it is statistically proven that they have weaker Jewish identities than those w/ 2 Jewish parents. An example, a friend of mine has a Jewish mother and he didn’t have a bris because his father did not want him to.
