#2 can be split into two sides, and not everyone believes one of those is sexual abuse.
Edit: Removed video link because the second half was gross and unrelated. May try finding another clip, but the first half was of Cenk Uygur from The Young Turks about a decade ago saying he'd legalize cases where the person pleasured the animal.
I'll be blunt: I don't really feel the need to argue about that point. It's sexual abuse.
