What is the halacha on proselytizing? If a Jew tries to convince a non-Jew to become Jewish, is he breaking any commandments or rabbinic decrees? Sources, please.
(I know there is evidence we used to proselytize 2000 years ago and that Pesachim 87b says we were exiled only so we can proselytize. But I am asking for the current halachic position.)
