This is an interesting take on the situation. It seems to me that the real core difference between conservatives and liberals is that conservatives believe that THINGS are amoral, and that most people are intelligent enough to handle their own affairs. Liberals, on the other hand, believe that things can be positively EVIL and that people aren't smart enough to avoid dumb behavior in and of themselves.
Now, if I understand you aright, you are saying that pornography, which is a THING, "devastates families, corrupts youth, and degrades humans." I respectfully disagree. PEOPLE MAKING STUPID CHOICES are what devastates families, corrupts youth, and degrades human beings.
Personally, I could give a rip about porn one way or the other. However, one has to admit that pornography has existed pretty much throughout recorded human history. It doesn't seem to have stopped the flow of civilization.
Where did you get that from? That's almost laughable! No, I retract that. That's sounds very libertarian. Why is child pornography wrong? That is just a THING according to your deductions here. When it somes to sexual immorality, I am finding out through many posts here on FR that conservatives and libertarians don't have much in common.
