Wow, impressive gymnastics you're doing here to try to make it ok to abuse animals.
Sure, let's just assume that it's fine and continue, I mean it's not like it just keeps on being proven wrong.
What is your point exactly? What good does it bring, to try to find ways to justify something that is likely harmful? What good does it bring you, to assume that animals that feel pain probably don't suffer still, other than just to delude yourself into thinking that it's ok for you to inflict pain to them?
