Exactly, child pornography is the abuse of a minor, and every law concerning it was created for the protection of minors. All is as it should be.
What you are suggesting is that even artistic representations of it should be prohibited, which is an entirely different issue altogether. It becomes less of a criminal issue and more of a social issue. Where does that rabbit hole stop? Should we be prohibited from talking about incidents of sexual assault of a minor? Are we verboten from even acknowledging the existence of child predators? Where does that line of reasoning stop? Rape is also a horrific act, and those who commit it are among the most disgusting and vile people who exist - does that mean, then, that depictions of it in fiction are to be expunged? Are we no longer allowed to have porn where the actors pretend to engage in a rape scenario? Is even depicting a rape scenario with animated characters too much?
You are arguing against free expression, you fucking communist.
