Well, I see the broad brush of sweeping generalisations has been applied liberally in this thread. Without getting into it too much, I would point out the following:


In the mid 1960s, the Dalai Lama was impressed by ethically vegetarian Indian monks and adopted a vegetarian diet for about a year and a half. Apparently he consumed primarily nuts and milk. Unfortunately, he contracted Hepatitis B and his liver was seriously damaged. For health reasons, he was advised by his personal physicians to consume meat. While he has eaten meat in moderation ever since, the Dalai Lama has repeatedly acknowledged that a vegetarian diet is a worthy expression of compassion and contributes to the cessation of the suffering of all living beings. However, he eats meat only on alternate days (six months a year). He is a semi-vegetarian, though he wishes to be a full one. By making an example of cutting his meat consumption in half, he is trying to gently influence his followers.

"While many of the great Tibetan teachers did and do eat animals, the Dalai Lama has broken new ground by publicly stating his case for vegetarianism. If we seriously consider the compassion inherent in His Holiness' advice and actions, Buddhist meat-eaters could similarly try to eat vegetarian at least every other day to start out with. Since Buddhists have taken vows not to kill, they should not support a livelihood that makes others kill. Even if one does not have great compassion for animals this would meritoriously save humans from performing heinous deeds. The power of each human being becoming vegetarian releases the most intense suffering of the animal realm—the agony of factory-farmed animals. This profound action can help slow the grinding wheels of samsara, bringing to a halt the cycles of suffering of the entire animal realm and influencing their eventual liberation. When animals are not just looked upon as creatures to fill our stomachs, they can be seen as they really are—beings who have the same Buddha nature as we all do.
