I am a meat eater. I have no qualms about admitting that I enjoy meat. I've gone stretches of days without meat, and miss it when I do. Obviously, people can live a healthy life as vegetarians.
I am not sure if I understand the difference between 'natural' an 'normal' here, as it seems that 'normal' would be a given if you thought it was 'natural'.
At any rate, I have hunted and fished for food. I'd be happy to eat vat meat if and when it is a satisfactory replacement.
there are societies in which it's abnormal to eat meat. https://en.m.wikipedia.org/wiki/Buddhist_vegetarianism
or think of it this way, it's normal to drive a car or otherwise ride a vehicle in American society, but definitely unnatural
