I don't think that should be illegal. The reason its illegal is stupid "think of the children" / "why are our kids having sex?" / 'sex is bad' voters.

However real child porn should be illegal.

That's what I said. "Unless child porn prosecution proponents can limit themself with some strict definition of child porn (which they would not do), I say we lose by criminalizing possession of random pics that were considered OK thirty years before." If the logical expression is true, real child porn can remain illegal. The problem is - the logical expression is false right now.
