>animal crush isn't illegal to possess/distribute, hell you can find it through a basic Google search on websites like Encyclopedia Dramatica
>snuff isn't illegal, given how there were zero prosecutions or arrests over people watching 3guys1hammer
>zoo isn't illegal and obscenity is never enforced
>you can seed terabytes of pirated movies, vidya, tv shows and so on through websites like the Pirate Bay if you really wanted to, and the only thing you'd have to worry about is your ISP throttling your connection, as copyright infringement is only a matter of civil court usually
So really, the only things banned in the US are CP and selling/buying bootleg'd DVDs that some dealer burns on a disc and sells for his own profit (although this isn't as common as it used to be, but I've heard stories of SWAT teams breaking down doors over this shit, not even joking).
Does any of this make any sense to you or do you agree with it? Nut hey, at least we're not Germany with their crazy ass piracy laws.
