Also, I personally think framing it as a binary or quasi religious decision is counterproductive.

I was vegetarian for some years, before ultimately deciding I just run better on an omnivore diet. But for environmental and ethical reasons I decided to make meat more of a side dish vs the center of the meal, and to mostly eat chicken vs more high environmental impact animal proteins like beef.

I think a lot of people that would never go full vegan can do well on this sort of less meat middle road.
