"They've legalized prostitution in some other countries. Why don't you go to one of them if that's the kind of place you want to live."
They've uesed government guns to enforce specified morality in other countries, specifically outlawing pornography. Why don't you go to one of those countries.
"Conservative Americans will fight to our last breaths to stop lily-livered liberals from turning our nation into some AIDS-ridden Needle Park"
Your completely missing the point, or more accurately purposefully ignoring the point. As a private citizen you are free to promote your morals as much as you want. The government is not a tool available for you to take those actions. The same tools you want to use to enforce your morality are being used by those "lily-livered" liberals to turn the nation into some AIDS-ridden needle park.
What you don't realize is that by using the same tools, you too are "lilly-livered" and just handing more power to your enemy.
No, your anarchist arguments against all morality in law are.
My arguments are what's fighting drugs and prostitution in the U.S. It's no coincidence that those who see no problem with porn also want drugs and prostitution legalized. They would turn the reigns of power over to gangster pimps who would whore out America's youth.
