Jainism

Yes, some sects of some religions take a compulsory stance on vegetarianism, but I was referring to the whole religion. I think Jainism is the only one where the whole religion in all of its sects and denominations have compulsory vegetarianism (not counting new religious movements).

Buddhists are very good at practicing vegetarianism in a few limited number of sects. Many Buddhists eat meat though. I think the "half" figure is mistaken though. According to Grok:
Even The Dalai Lama isn't vegetarian. From what I remember from his "Freedom in Exile" book, they won't harm an animal, but often take meat, dairy etc from others.
Kind of like most meat eaters I guess.

I am amazed you are using Grok with all that it stands for :(
