That being said, someone mentioned that Bible Stores and Gun Shops are protected by the constitution, but that is incorrect - they are subject to zoning regulations the same as smut shops - what happens to one can easily happen to others... I am very wary of opening this can of worms, because if the community wins on this one, what's to stop a community of left-wing commies from deciding they don't want gun shops around their kids???? Where do we draw the line???
The way I see it, "obscene" material is NOT protected by the constitution when in the public arena (i.e. TV, Movies, Billboards, etc...) - as long as it's behind closed doors, it IS protected. And I doubt very seriously that these shops have tables outside their establishments with their wares displayed for everyone and anyone walking by.
For instance, many communities and states have anti-gambling rules, because the voters know that gambling "businesses" change the fabric of a community. Most gambling, last I saw, didn't take place on sidewalks or in full public view.
And there, again, a little gambling over a poker game in one's living room is not the same thing.
