Stores sell what is in demand. The store owner has his/her own nisayon about what to sell or not sell, but to put the onus of how people dress on the store owners, that is just plain silly.
Agreed. The supermarkets in frum neighborhoods don’t sell treif because nobody would buy it.
There may be a point to think about here, though; if frum grocers would sell tarfus as well, would people be so outraged that they would take their business elsewhere? If so, does the same standard apply to clothing stores?
Sam, what you are describing is the difference between not caring about a breach in tznius, and not being aware of one. Certainly, the latter is not ideal, but yes, there’s a world of difference.
