Only if you eat the brain or spinal column, which I was careful to add. Otherwise the risks are as manageable as with cow meat, i.e., parasites and bacteria. Given that you’re okay with eating cats and dogs, and now simple-minded humans, what’s to stop me from killing and eating you? I mean, all anyone needs to assert is that they’re mentally superior to their food, what’s off the table for you?
I’m sure mass scale cannibalism might actually be as good for the environment as a plant based diet. Maybe you’re on to something. We’d be so morally consistent!
