It's not initiation of force when you have a choice not to look at his pornography. If you want to form a protest group to ostracism him you can do that so long as you don't initiate force on any person. I'm not into porn. Some people are just like some people would ostracize Flynt. But if you get the government to initiate force against Flynt there's no stopping somebody else from getting the government to initiate force on you because they don't like something you do. That would be using the government to force their version of morality on you.
As if the Founding Fathers fought for the right of people to manufacture and consume the most degrading of porn, which is nonsense. "Don't ban pornography because then someone else might decide to ban puppies, or daisies, or saying the Rosary!" Such is the line of moral-cowards. Pornography, we were told by the liberals, would remain in the homes of consenting adults. In reality, it has flooded our culture, and slaps you in the face wherever you turn.
