Traditional conservative values are relative. Western women are forbidden from going topless in public even though men are allowed. They also can't show their pubic hair but can show their head hair. The differences seem kind of arbitrary.

Pedophilia as a sexuality is harmless. It's only a desire. We shouldn't assume all pedophiles have had sex with children. Probably the vast majority haven't.

Consent isn't so meaningful when it comes to animals. Females of some species don't consent - they're forced to have sex by the males of their own species (walrusses I think). So clearly consent isn't actually something we require from animals. As Lawton said, we do far worse things than rape. We torture dogs by locking them in solitary confinement for most of their life. We of course kill animals just for fun. It's hard to imagine that rape (assuming you can't measure consent somehow) can be worse than psychological torture and murder combined.

Harm to children isn't why we don't like incest, otherwise we'd be banning people with even minor genetic problems from having children (heart disease risk, low IQ, etc). We don't like incest because it's a weird sexual deviancy which repulses us just like homosexuality does to many people.
