The only way I know, the defense bar being as well-greased as it is, to discourage a bunch like that seriously (and all the big outlets are both fronts for prostitution and run by the Vegas Mob -- or so said CBS News 20 years ago, when they described the Mob's decision to push porn in the faces of every citizen of the U.S., in order to get to the young men) is to organize a well-run, very tight marshmallow-roast ring. Or something like that. There's no legal way to fight it any more, courtesy of the liberal Supreme Court justices of the 1960's.
The same problem the poster has with supersmutshops up by Gainesville (I know the place you're talking about), other States and Indian reservations have with big liquor stores and fireworks stands. Coming soon: Drug shops.
In an ideal world, a Texas patriot would buy out the place -- it's called DW's -- and put a gun store there. Note the absence of a /sarc tag. I honestly think a nice big outlet stocking ammo and firearms would be a very fitting "Welcome to Texas!" greeting, reflecting our cultural values and represent the freedom we enjoy courtesy of the Second Amendment.
And, best of all, it would drive the liberals (yes you, Wendy Davis) crazy in the same manner the smut palace does to me! :)
