As a citizen, I sure would like to have a say-so in my state, or my city, or my community whether or not to allow porn, bookstores, etc.
Unless you're saying that porn should be a protected right, like free speech or freedom from illegal searches and seizures. That wherever I go, I have to accept it? Freedom for thee but not for me?
You already do through zoning laws. All communities, towns, etc... have the right to prohibit the establishment of adult bookstores, strip clubs, etc... within their jurisdiction.
However, your communities should not have the power to not allow me to access porn on the internet if I lived in that town, or prevent me from having playboy delivered through the mail, or to watch porno movies on my DVD player.
Also, Alabama has banned adult bookstores throughout the entire state and the law has been upheld. So, the ability to do what you desire is available.
