If the idea behind bestiality being illegal is that the animal can't give consent, or that it's animal abuse, then why are we allowed to kill animals without their consent? Why are we allowed to torture and abuse them in CAFOs? Why aren't factory farms addressed in the Animal Welfare Act?

Prove to me that the law isn't just religious bullshit. Show me how there is no contradiction in killing* torturing animals for food, but making laws to protect their asses.

*discussion has transmogrified into something more specific.
