Which of these should be legal?

[minionofmidas]

Topless women in public - aye
Full nudity in public - aye. Although hiding behind a tree and then flashing at close range to terrify others should not.
Child pornography - nay (what's a child though?)
Minors buying pornography - aye
Pedophilia - See John Dibble. Also, lower the age of consent.
Zoophilia - nay (but see John Dibble)
Necrophilia - nay (but see John Dibble). Although I sort of like Richius' form.

No, but there is no reason to apply the consent test to an animal just because you apply it to a human.  You're being silly, Ebowed.

No, I think anybody who wants to legalize raping children, animals, and corpses is the silly one.

Assuming we drop the fiction of an age of consent, the term rape would only apply if the 'child' were unwilling.  As for corpses, the fellow might as well be ing a hole in the earth - anyway that is what the dead will be very soon. 

I am sympathetic to the idea of preventing cruelty to animals, but I don't think that needs to automatically include a blanket ban on sex with them.  Obviously a cow or pig would scarcely notice.

I never heard of anybody doing a pig. IIRC sheep and goats are the favored animals for the purpose, by men. By women, dogs.
