Should people be put in prison for hentai?

Do you think that hentai depicting fictional drawn hentai characters that are under 18 having sex with adults (lolicon or shotacon) should be in prison and labeled a pedophile? If you believe so, how is this different than if you were incarcerating people for drawing up an image of the Muslim prophet muhammed?

I personally don't believe anyone should be in trouble in anyway that leads them to be in prison and have their life destroyed because of a drawing even if people found it disgusting morally speaking. I support the first amendment like a real American with liberal values should.
