Lilmod, in fact, I know a Chareidi rav who tried to justify the fact that some “frum” guy helped people receive insurance payments even though they were not insured by saying that he did not personally profit but just wanted to do chesed (interestingly, the Torah says that marrying one’s sister is chesed). So far as I know, OO rabbis say that certain acts are sins but that the sinners should be mekareved by looking the other way.
Time, your points are also true about people in other factions. There enough opinions for people to pick and choose. There is even an opinion that it is permitted to rob a goy (Baba Metzia 111b). Ok so it’s not the halacha but why can’t one rely it anyway? Not saying lashon hara about a fellow Jew? You call him a Jew? Not derided a talmid chacham? You call him a talmid chacham?
