regarding earlier posts about causes of mabul:
meshech chochmah (parshas b’shalach)suggests that while the individual is mainly punished for bein adam l’makom, communities are punished for bein adam l’chaveiro (see there many sources). Therefore, he says, the arayos of dor mabul, while making them deserving of punishment as individuals, would not have caused global destruction, but as a tzibbur they deserved punishment for gezel, shalom etc.
As far as our generation, I don’t think we need worry about the global effect, because it is clear from all the sources that after Matan Torah, only Jews have a cosmic spiritual effect.
Can someone explain to me why we feel the need to protest laws against mishkav zachar ? It is not the only thing labeled as ervah for bnei noach, and others are quite legal and common, and yet we don’t lobby for legislation for them!
