Whether people meme it or not isnt something I'll really criticize. I'd say I'm a pretty big advocate for the ethical treatment of animals. Obviously I'm biased because while I do abstain from eating animals or animal byproducts, I make an exception with fish.
Anyways people meme and joke about far darker/more serious matters. So if the only thing people home in on is "funny noise", well that's that. I'm in little position to fault them for it.
