I guess so. It depends on the context of course. If you're stuck in the wilderness, and there's no other food sources available, I guess it's ok to nibble on the weakest member of your party.
I wouldn't be against it as a form of punishment too. Say if someone does something really bad, it would be fair if the whole town ripped off their flesh and ate them alive.
And then there's the case of zombies. It's ok for them because they don't even understand what they're doing. They just do what comes natural. But then I guess that begs the question of if it's really cannibalism. Are zombies still classed as human? But I guess you never see zombies eating other zombies. Maybe zombies are against cannibalism?
Anyway, yes I guess I do support cannibal rights. We are living in a democracy. Free speech and all that. Who am I to say what's right and wrong? If women can vote, then why shouldn't people who choose to eat other people have the same rights?
lol, an expert in this field.
