No, and neither should artistic depictions of children in sexual situations - with reasonable obscenity laws in place, of course.
No matter how appalling or distasteful, the government has no place to regulate art or inanimate sex toys. The First Amendment still applies, even to things we don't like.
And, if it prevents a pedophile from going after a real child, I honestly don't see the reason to ban them.
I mean, the First Amendment seems pretty obviously to have been referring to political speech, not what one wanked to.
It just says speech
And it’s okay to punish people for shouting “fire” in a crowded movie theater because...?
It's only punishable if there is no fire and it creates a panic. Freedom of speech is not limited to political speech.
