I'm always confused by people who are more offended by animal violence than human violence. There's something inherently wrong about that point of view.
Reminds me of a scenario when I tell anyone about the band Snot, which I'm sure not too many people know. The singer died in a car accident. When you tell people that, they're like "Aw, really?" Then when you tell them that the dog on the cover of their cd died in the accident too they actually get upset. "The dog?!? No!", genuine shock and dismay finally in their voices.
But.... a person died too! What's more important here?
I've seen pictures and videos of how animals are treated, and while yes, some of the conditions they are put in are fucked up... it's all food in the end.
