A600, or should I say 300 (my opinion of you keeps dropping with every posting of yours).
Halacha defines how people should dress. If people are dressed within the guidelins of halacha, no matter then no matter how little you care for their mode of dress, you have no right, according to halacha to call them “grub and prust”.
So, your’e all for elevating a makom? Then the next time your shul collects money for renovations, tell them you’d rather daven out in the street, you want to elevate the Makom. (Clearly – i am being dan likaf zchus – you misunderstood what i wrote about this, but it has nothing to do with tznius so will leave it).
Again, nobody is asking you or advocating that you dress in a way you feel is “grub and prust”. On the other hand, calling those who are within the bounds of halacha, as guided by their poskim, grub and prust, is definitely grub and prust and falls outside the bounds of halacha.
