I dont know this persons goals, but conversion should be reaccessed in Judism. Up until we were confronted with Christian Rome, we openly looked for converts to the Torah. now it seems we are stuck in post European Ghetto mentality, where we reject all interested parties. Now this does not mean that conversions should just be as simple as Christians or Muslims, but if a gentile wants to become Jewish by following Kosher rules and Holidays, and learning Hebrew etc, why are we allowing the disitergration of Jews to Gentiles, but not trying to increase our numbers by attracting the best of the Gentiles, which many in our own family history long lost to us, might have been.
