When other people bake and eat a potato, they're eating. But when I do it, it's homicide and cannibalism!
Are you saying that it's okay to eat people?
I don't see why wouldn't be normal, it's just food it's not like anything bad happens from eating people.
I think that this joke is really disgusting, not only because it endorses cannibalism, but also because it's disrespectful to people with disabilities. These kinds of jokes are harmful to people with disabilities because they dehumanize them, which leads to discrimination. I think if you learned more about the struggles they face, you'd be less likely to say things like this.
