[Modernman]

God did not give man freedom to do evil, but to do good. God does not give us a right to do evil. The idea is self-contradictory.

You have every right to do evil. However, there may also be some consequences from exercising such a right.

In any event, manga is not evil. Inanimate objects are neither good nor bad.

You have every right to do evil.

We do? How do you know?

Where do rights come from?

For rights to be unalienable and binding on all of us, they can only come from God. God's essence is goodness. He doesn't will evil, so He cannot uphold a right to do evil.

However, there may also be some consequences from exercising such a right.

Uh, yeah.

In any event, manga is not evil.

How do you know that? It's pornography. It serves no good purpose. It only serves to corrupt morals.

Inanimate objects are neither good nor bad.

That may be true with naturally occurring substances, but that is not true for works of art. This "art" serves only to corrupt morals and has no redeeming value.

(All existing things possess ontological goodness inasmuch as they possess existence. But existence is not part of the essence of any thing, except God.)
