“Problem #4886 with Lubavitch:
There is a Lubavitcher who doesn’t know who Reb Shamshon Refael Hirsch is.”
You joke, but I actually believe these things are more of an issue than the philosophical stuff that gets people worked up here. Chabad claims to be all accepting and interacts with everyone, yet within the frum tzibbur, Chabad is super isolationist. And, no, it’s not “everyone else’s” fault.
