That is your opinion, but the Founding Fathers disagree with you. That’s all that matters. They knew porn and they didn’t make a clause dealing with it. Whatever their thoughts on porn were, they didn’t want the government to deal with it.
Even though some people in dark corners and alleyways might have passed around tattered shreds of cartoon naked women, nobody had access to pornography in the time of the founding fathers.
The number one talking point of the anti-American globalists is that it was just as available as it is in our time.
The founders would disagree with you. Our Constitution is not a suicide document.
