Honestly no idea what you’re talking about, here.

> When you say vegan stuff like that, you should be more precise: people do not need to eat meat to survive. Survival and good health are on the opposite end of the spectrum.

I needn’t be more precise. Meat is not required for survival or for good health. Exception being if one’s situation demands eating meat. For somebody reading/commenting on HN, eating meat is almost certainly a decision, not a requirement of any sort.
