ZD,
Fascinating observation.
However, I have never seen people wearing “strimels” or “Beckashers”(sic)at any of the funerals that I have unfortunately attended, even among the most chassidic.
Can you guess why? According to you that would be proof that Jews nowadays do not wear Shtreimlich or Bekeshes, yet that is clearly not the case.
So how do you explain that?
