So you agree? Our ideas of right and wrong are largely arbitrary so we aren't actually very good people compared to our ancestors. Your main concern is that the examples I used to show that aren't as good as showing that we arbitrarily eat pigs but not dogs?
Your argument using consent seems to be more arbitrary than it needs to be. The legal definition of consent isn't the reason we don't allow those things. That's just a tool we use to decide if it's a crime. The reason we don't allow them is probably because it can psychologically harm the children. I'm not sure about the reason for animals but it's probably more similar to the reason we don't eat dogs but we do kill and torture them. That is, it's not for the benefit of the animals, but something arbitrary in our culture.
