“Who is on the proper hashkafic level today to make up or impose chumros today?”
“If people believe this is an actually untenable Shittah, they have a right to call out.”
This is the issue here. It is a hanhaga that a particular community has imposed upon itself. It makes no claims that this is the halacha. It imposes this hanhaga on nobody outside the community, and quite frankly I doubt anyone within the community sees it as an imposition.Why do you claim it is untenable? Who said it is? For you perhaps this is an imposition and a situation that is untenable (with all its dictionary definitions), but, as an outsider to this community it doesnt have any bearing on your life one way or another, so why do you care?
