blink_, could you list off the nutrients that you supposedly are unable to get from any source?
I know several vegetarians and vegans (I am also a vegan) who do not take any supplements who are not pale and weak as you suggest. I know at least one vegan who is slightly overweight, rather than being as thin as a lamppost. I know at least one vegetarian who is extremely physically active, rock climbing and hiking and going on bicycle tours as often as she can. I am also pretty physically active, riding my bicycle long distances regularly. With a wide and varied diet, all of the necessary nutrients that meat contains can be acquired without much difficulty.
As far as I am aware, there is only one exception, which is vitamin B12. But we need that only in very small amounts and it is added to a number of things, so even that is not as hard to get from non-meat sources as you seem to think.
to the OP: I don't think eating meat is cruel. It's obvious that humans are omnivores by nature. But in todays world, we are
capable of excluding meat and still being healthy, unlike millenia ago, so I don't think that is relevant anymore. I do think it should be excluded from our diets as much as possible, though, for the sake of efficiency. The resources required to produce meat are absurdly great in comparison to producing produce. In a world where people starve to death on a daily basis and the excessive use of resources is destroying the environment, to keep relying heavily on such an inefficient food source seems to me to be unethical.
I agree with blink_ on the subject of vegetarians who eat fish. I think vegetarianism is being forced upon society just as much as I think Christianity is being opressed in the USA. Omnivores are in the majority. There is a vocal minority of vegans and vegetarians who are trying to make change, but I don't think they could opress you even if they wanted to.
As for health, I think vegetarianism or non-vegetarianism is irrelevant. A vegan can eat a wide variety of foods and be extremely healthy, and an omnivore can eat steaks all day and get scurvy. You can be healthy or unhealthy with either dietary choice.
eta: In terms of cost, it's more expensive if you rely on meat subsitutes rather than eating a wide variety of real food. I stopped eating meat, and I've honestly lost the desire to eat it again. I for one do not waste my money on replacing it.

Lastly, the grain we save by not using it for raising livestocks - yes, it would feed everyone on earth, but as if it's going to get to the poor people.
Why wouldn't it? Supply and demand. If we suddenly had a massive increase in how much food was available, meaning a much greater supply, why wouldn't the cost decrease proportionally and make it easier for the poor folks to eat?
