Store owner's name, Munirah Kabani, kinda gives a hint, don't you think?
And yeah, open season on Muslims might not be that bad an idea; wouldn't be any reflection on "freedom of religion" either, unless you define "religion" loosely enough to include the degenerate belief system called "islam".
Let's see. Dictionary.com defines "religion" thusly:
Belief in and reverence for a supernatural power or powers regarded as creator and governor of the universe.
A personal or institutionalized system grounded in such belief and worship.
The life or condition of a person in a religious order. A set of beliefs, values, and practices based on the teachings of a spiritual leader.
A cause, principle, or activity pursued with zeal or conscientious devotion.
Looks like Islam qualifies. Sorry to bust up your Krystalnacht party.
