I wouldn't go as far as saying it's exclusively for pleasure. Generally when I eat meat it's for pleasure, but also because it's good protein, and I need that. Of course you can get protein elsewhere, but my point is that there's a difference there between eating an animal, we do need food, and making an animal suffer just for entertainment. You can argue that both are immoral, but I would still hold that there's a significant difference.
Perhaps my greater argument is: If the point of this comic is to make some observational humor "look we don't harm animals in movies, but we also eat them! how strange!" than, it's not too original or funny. (for the record, I've found some of his comics very original and funny). But if his point is to bring up an issue, than he's doing the argument a disfavor by glossing over all the nuances and complications.
Also, I don't even really have a strong opinion on the matter, I think I just felt like arguing today.
