When one of my friend's gets a response like "That’s an awful complicated way to say “no woman will have sex with me and I’m angry”", or another friend has to leave Twitter because she's getting relentlessly mocked about it... It ain't because they don't care...
Hell, that whole meme page misses the point a lot of the detractors were trying to say.
The problem isn't the sight of the dead dog, but the seemingly random placement of the dead dog. Unless you pay attention to the details, which is definitely hard to miss, you'd have no idea why a dog is there in the first place. You're expecting a house full of fishmen and mutated workers, then BOOM. It's just an unexpected sight. The people bitching about the people bitching keep neglecting that point and are opting to go for the strawman argument of "BUT IT AINT THE ONLY DEAD ANIMAL YOU DONT KNOW HORROR" just to join the mob mentality.
