Yes, your links indicate that it's even more radical than you described at first. It's not about merely ending suffering due to overcrowded factory farms or inhumane slaughtering/lab testing. It's not merely about not-killing animals. It's far broader than that. In fact, veganism is only a means to an end for animal liberation activists. They desire that animals achieve equality, or should I say, have equity, compared to mankind.

So I apologize for assuming that you were attempting to narrow the focus, but once again, you don't speak for all vegans, and Hindus, Jains and Buddhists all still exist.
