It goes without saying that this absolutely will not pass constitutional muster.
You can categorically try to ban pornography but the second you try to ban it based on its content and not based on it being pornography you no longer have a leg to stand on.
I wish there were some way to have criminal consequences for deliberately passing unconstitutional laws. It definitely feels like it's some kind of sedition, violating your implicit or explicit oath of office so profoundly.
IMO, as depressing as the thought is, we are rapidly transitioning/declining to a post-Constitution America. It makes sense, because conservatives have never really embraced the notion of a secular document as the law of the land, which can be used to shield individuals and minorities from their abusive moralistic patriarchal regimes. Now they have a chance, many chances in fact, to "right the wrongs" they suffered as a matter of enlightened compromise made in good faith. And we are seeing it everywhere.
