I have always marveled at the way Lubavichers say, as sechel has, that all Jews are equal, and that there is no difference between a mechalel Shabbos and someone who keeps Shabbos, and the like.
And despite that, on Shabbos in Chabad houses they either use mevushal wine, or they cover the bottle in case someone who doesn’t keep Shabbos looks at it. Still, no difference between someone who keeps Shabbos or someone who doesn’t, is there?
And lets not forget how the shechita of many mumarim is kosher, yet Lubavichers only eat the shechita of other Lubavichers. (Actually, according to what we have been saying for the past months, in some cases that may indeed be shechitas mumar.)
