You still don't get it. Whatever you're going on about is only "obvious" to you. "Cultural norms" are your judgements and your biases. There is no mandate to "suffer" from a "lack of nutrition," millions and millions of people are vegetarian and just fine. I'm one of them. My CBC and vitamin panel came back as 100% normal.

Meat agriculture is killing us slowly like cigarettes and cancer, and kills us quickly.

1918 most likely zoonotic route:

Birds -> pigs (at a "piggery") -> humans.

2019 SARS-CoV-2 most likely zoonotic route:

Bats -("wet market")> humans.

You seem to emphasize edge-case FUD and "other" people who don't agree with your value judgements rather than opening your eyes to meat agriculture as a slow-moving existential threat to our survival like and causing climate change.

It's very unfortunate that you're so narrow-minded.
