I’m not sure you want to vilify a community. L”H of a tzibur is a grave, severe sin. (Now you have to make a mass mailing begging mechila.. “Hello this is a recording on behalf of gavra_at_work, I beg your mechila, press 1 to be mochel..)
I thought about it before I submitted, and respectfully disagree. If they believe their Shittos are correct, then Kol HaKavod to them. However, they can’t make the claim that they are “authentic Yiddishkeit”. Those who are machshiv Limud HaTorah (not who your great uncle or grandfather was) are the real torch carriers of the Ribbono Shel Olam. Those who try to add things other than Torah as “mitzvos” (such as the Denier number of stockings) have added to Yiddishkeit what Hashem has not asked.
However, you are correct that certain comments made by a certain “great nephew” have gotten me livid. When he apologizes to whom he slandered in public, I will do the same (even though I believe there is no Halachic reason for me to do so).
