“BneiBarakObama”
Wow, that’s a good username. I can see you and me being buddies. I can also see us constantly being accused of being the same person given the similar nature of our usernames.
“If one has a minhag to not fulfill a mitzvah and he is unable to find a substantial Heter then he would still be mechuyav to fulfill the mitzvah regardless of the baloney he received in his community.”
Well, the short answer is yes, but I think you misunderstood RSo’s point. There is actually a substantial heter to not sleep in the sukkah that many non-Chabad people in northeast America rely upon. The problem is that Chabad will never say they are relying on this heter. They instead created their own logic and now refer to not sleeping in the sukkah as a chumrah. They institutionalized the heter to the point that those who could otherwise sleep in the sukkah just fine don’t.
What RSo and others were doing was differentiating between this argument and a public criticism of all who do not sleep in the sukkah. If it were the latter, Chabad would call us hypocrites given that [probably] most Jews in the NYC area do not sleep in the sukkah either. The way I see it, it’s a self-awareness problem. If somebody has to rely on heters and be meikel every now in then, fine; that’s just being human as long as they’re honest about it. But, this need to redefine reality so that they can think of themselves as “big chossids,” who have a lot of “chumrahs” even when that’s not the case is just weird and almost kind of sad.
