Pls no way he looked “to cool”. I think u can agree that a rebbe has to be someone to look up to. He can’t be wearing stained tie and ripped suit either.
He's a younger cool kind of guy. So I believe it. He was too out in the open.
And at least in Israel many many of the Chassidish Rabeeim I saw looked like no one ever taught them how to get dressed and far from what I consider to be meinchlicht.
The idea to look proper is one thing. How riding a bike became to be seen as improper is where the problem is.
