That sounds great until they pass the "Freedom to Produce Child Porn Without Criticism Act" and you wind up in the slammer. Just ask the pro-life movement.
Meanwhile, sexual deviants get their jollies and real children suffer real harm while we debate whether or not the first amendment was intended to protect child pornography. The only thing I know for sure is that the founders wouldn't have had time to debate this issue, they would have been too busy making sure child-molesting deviants found the limits of the first amendment at the end of a rope.
I would if I could but I never hear a peep out of the people that make up the movement anymore.
