“Username was saying Lubavitch has a “claim” to גן עדן & גיהנום because they talk about it in depth, whereas non Lubavitchers don’t”
I think he was making a direct comparison between Chabad Chassidus and musar, not Chabad people vs all other groups. It gets hard to follow what points are being argued when the discussion went from “Chabad doesn’t do mitzvos for Hashem’s sake alone” to “Chabad doesn’t put enough thought into schar.”
Sphardim do seem to focus on schar and segulas a lot more (on average) than Ashkenazim. I think most posters here can recognize that without saying that one approach is abjectly better than the other. Why can’t we do the same with Chabad? I hate to say it, because I do think this has been a productive thread, but it’s starting to feel a lot like nit-picking at this point.
