Under age characters illegal in USA?

it was great that they ruled that the law was unconstitutional but you would also have to understand why they wanted that law. in the early 90's, pedos claimed that the pictures are digital images and that they couldn't tell if the child is real or not. that is why they want to include virtual child pornography because they feared that in the future majority of it would have children that didn't existed and since they didn't have a law against it, then they couldn't go to jail. but when that law was found to be unconstitutional, they created a new law that made it illegal if it was realistic and that you couldn't tell a difference between the image and an actual child. Since loli is not realistic and any idiot can tell the difference between anime and actual people, loli can only be illegal if its obscene. that is why loli is legal just any other type of porn that is legal in the US.
