Your self-defense is to create or support the creation of the content YOU want to watch instead getting the socialist, nanny state to limit my options to watch what YOU approve.
As I mentioned previously, in the post that you originally disliked so much, retreat is no longer an option. I have not watched television in years. I dont listen to the radio, I rarely go to the movies. And guess what? This approach doesnt work. I still get slapped in the face with a degrading popular culture at every step. To say if you dont like it dont look is like saying if you dont like the polluted air dont breathe. And I have come to the conclusion that libertarians dont believe this lie either. I think you like things just fine the way they are, and are more than happy seeing social conservatives neutered by passivity. You use this argument only because things are going your way. You know very well that simply turning the channel accomplishes nothing, and would be the first to scream if our popular culture was saturated with beliefs and actions with which you did not agree.
And another smart bomb slips in under the radar for a pinpoint surgical strike against disingenuous libtertarian posturing.
Basically, you are saying you don't like your fellow man's tastes, which is fine. But against the majority's (popular) fashions and behaviors (culture), I'm afraid your only choices are either to kill all of those with whom you disagree, rant on in misery while people roll their eyes and laugh as they walk by, or to become a hermit.
As an individual, you have many choices, but unless you withdraw from society completely, I'm afraid you are going to have to just endure the rest of us.
