Yea, one thing I feel is that vegans really are letting perfect be the enemy of good. While I do empathise and am eating less meat myself, I feel like screeching on people being omnis is missing the forest for the trees; if most people did like what you mentioned, eating meat once a week, that's 6/7th less animals slaughtered. Along with the reductions in emissions and whatever environmental impact too, of rearing so many animals for their meat.
