But frankly, being a vegetarian is not a superior moral choice. If you are a vegetarian for reasons of health it is one thing. But vegetarianism as moral campaign is deluded. Millions of animals large and small die to bring vegetables and grains to our plates every day. But over and over again vegetarians justify this claiming that the purpose of such agriculture is not to kill animals, so therefore, they morally excuse themselves from culpability in the death of countless millions of creatures.
It seems to me that your argument is against the modern agriculture industry not vegetarianism per se. If vegetarianism could operate without the use of organic or inorganic pesticides in a sustainable way perhaps that would be the superior moral choice. This isn't feasible on a large scale currently, but vegetarianism even in its current state would be a progressive step towards that end while non-vegetarianism cannot be. In the same way that world peace is not achievable currently, and many may technically die because one does not join an army to protect oppressed countries by killing oppressors, this is not a valid reason to join the army.
When people stop killing animals for food, I will stop eating meat. Until then, I won't. It is pretty simple. I personally don't care what diet people have -- but the saccharine fake compassion holier than thou attitude of some vegetarians is pretty pathetic. So if your conscience won't permit you to eat meat, great, don't eat it. My conscience won't permit me not to. But don't lecture me with some lame ass criticisms and poorly cited arguments from Abhidharma (which incidentally is a Hinayāna system in which meat eating is permitted). If people wish to follow common Mahāyāna and avoid meat, fine. The Hevajra tantra states however "Those who eat meat have compassion."
If you really want to follow the common Mahāyāna POV, not only must you avoid meat, but you must avoid onion, garlic, scallions, wine, and so on. So if you are going to do down that road, be consistent. Don't eat onion, garlic, meat, drink wine and so on.
As I pointed out, if people grass fed their cattle in a proper way, for both dairy and meat, we could reverse 200 years of carbon release in ten-twenty years.
So far no one has answered my observation that whether eats meat or not makes absolutely not one whit of difference concerning whether one will become an awakened person or not. But there are apparently some people think that their choice diet makes them superior buddhists -- well, screw that, what bullshit -- load of religious crapola disconnected with reality.
