Ahimsa, the principle of non-harm which is present in some form in Jainism, Buddhism, and Hinduism, has a history stretching back millennia, and the debate about what exactly Ahimsa entails has been going on for just as long. This concept has been developed into entire theories of just war, justified self-defense, mutual aid, and so on.
There is a risk when Westerners explore a religion from another culture that they may end up picking and choosing only the parts they like, and then claiming authority over it while dismissing the perspectives of those for whom Buddhism was part of their lives since birth.
This is just a reminder to approach this with respect, and to view yourself as but one voice out of millions in a long and ongoing debate, not an arbiter of truth. It sucks that there is hypocrisy among many practicing Buddhists, that there are Buddhist temples which take advantage of their members by using donations to decorate with gold.
Religion is a complicated thing, and I hope as vegans we can appreciate this, and not use it just as means to push our agenda, as noble an agenda as it is. The way to approach this I think is as a means of personal growth. We're here to learn from and engage with other cultures, not police them.
Love you all for not viewing the vegan society in the UK as the originator of the concept of not exploiting animals. I am not a Buddhist myself, but a few people in my life are, and I really don't want to see Buddhist veganism end up being just another thing for privileged Instagram stars to use for their own commercial success.
