It was scandalous, even immoral, to show your ankles as a woman in Victorian times 1837 -1901.
The very definition of “pornography” and so called “decency” changes a lot over time.
The idea that any of this is new, is simply put, made up: https://en.m.wikipedia.org/wiki/History_of_erotic_depictions
The struggle between decency (whatever that is for the day) and those breaking the social norms has always been the case, even in other places.
The Vatican Sistine chapel is full of naked people, and that was fine at that time although there too you had conflict between different ideas of what’s considered decent: https://www.througheternity.com/en/blog/art/nudity-and-controversy-in-the-sistine-chapel.html
For the Greeks making naked pictures and sculptures was fine, you just had to give them a small penis, since a big penis would be vulgar: https://www.artsy.net/article/artsy-editorial-ancient-greek-sculptures-small-penises
But then the Romans thought the penis was a symbol of power and good luck, and the bigger the better. They had frescas, statues, walkway pavers, even doorway entries were adorned with giant penis in places like Pompei.
None of this is new.
But, don’t be part of the problem.
—For liberals, it’s ok to crap all over the US Constitution when it comes to environmentalism and social justice.
—For many self professed conservatives, it’s ok to crap all over the US Constitution when it comes to national defense, their idea of morality and public safety.
Both want to throw the US Constitution out of the window, they just have different values/priorities. The “conservative” wants to ban an image of a nipple to protect a kid, and the liberal wants to ban your guns to protect a kid. Both are full of $hit.
Nothing you said changes the fact that the history, text and tradition of the US Construction contains nothing that prevents the law from banning indecency.
The Construction is like a contract. It means what the parties who entered into it meant and understood it to mean. We don’t get to write new stuff into it without amending it the proper way. The idea that the framers intended the right to free speech enumerated in the first amendment to grant the right to deliver depictions of graphic sexual acts to children is ludicrous.
