The Hasid who says he is a heretic, yet continues to call himself Shtreimal, dares us to guess which of the big three sins he's committed.
This is too easy: Shtrimy doesn't believe in higher powers, so idolatry is out. And murder seems unlikely, especially for a soft-spoken and willowy Hasid.
This leaves us with adultery, or giluy aroyos, but adultery comes in many forms. What specifically was Shtreimy's sin?
Though adultery includes voluntary sexual intercourse between a married person and a partner other than the lawful spouse, Jewish law says other acts of immorality can fall under the adultery rubric. If Shtriemy committed adultery, it may mean he betrayed his wife with a hot hasidic hussie, or it might simply mean that he has a porn collection.
I'm rooting for porn collection, and not least because the porn collection would be a sin against god alone, and not against his wife and children, too. I'm sure the Rabbis would agree if the mistress was married and Jewish, but what would they say if Shtreimal had a non-Jew on the side? A non-Jewish mistress, I recall, is permited under the letter of Jewish law.
I'd like confirmation from a Rabbi. If you have smicha (real smicha, not the kind that comes in cracker-jack boxes) please answer this question:
What gives greater offense to God? A porn collection, or betraying your wife with a non-Jewish mistress?
