Buddhist attitude towards animal life (and indeed any life, and even the inanimate) is based on non-violence, as opposed to the attitude of Abrahamic ideologies, such as Judaism, Christianity, and Islam, which is one of murdering and violence.
Indeed, the demented Abraham, the very forefather of such Abrahamic ideologies including Christianity, was to the point of perpetrating the murdering of his own son Isaac, as a ritual sacrifice, when he was allegedly stopped by “god”, a story worth the guest of a madhouse.
Also, almost all of of the 613 Jewish commandments (“mitzvah”) are about the ritual performance of animal sacrifice. Their “kosher” food is the product of cruel animal sacrifice, and is forbidden in many countries. The same applies to the Islamic “halal” food.
The Old Testament (the Jewish Torah) even praisingly records an instance of human sacrifice perpetrated by one of his “prophets”, Jephtah, against his own daughter.
Besides, the Islamic “feast of sacrifice” (Eid al-Adha) is an inconceivable bloodbath, and every pilgrim must sacrifice a lamb or a goat, or join the sacrifice of a cow or a camel. In Indonesia alone, for example, some 800,000 animals were sacrificed in 2014 by its Muslims on such festival. See details here:
https://en.wikipedia.org/wiki/Animal_sacrifice#IslamThe Apocalypse of John proposes the murdering of most of humantity because of its lack of ”faith” in Jesus. And Jesus himself was supposedly sacrificed by his own murderous “father” (which they call “god”) in order to wash away the “sins” of humanity, and the celebration of such an obnoxious murder is celebrated by millions of Christians worldwide in the ritual known as the “eucharist”, when they eat the flesh and drink the blood of the rituallly sacrificed victim, Jesus.
Specifically, such murderous ideologies see animals as deprived of a soul, and as mere objects of use given by their “god” to humans for their enjoyment, as prescribed by the book of Genesis. And, according to the Jewish Talmud, non-Jews (which are derisively called “goys”) are also to be included among the animals, to which their “god” merely gave a human form so that they can better serve the humans, that is, the Jews.
All of this is in stark contrast with even the strict animal protective laws passed in Hitler's Germany forbidding any cruelty against animals including against guinea-pigs, such as vivisection. This places Abrahamic murderous ideologies in an embarassing situation, as they manage to be way more brutal than even a so-called anti-semitic dictator!
Engaging in or opposing animal sacrifice is indeed the main characteristic distinguishing Dharma from the “religions” of the barbarians “mlechccha”, according to the Kalachakra Tantra. Followers of the Vedic religion were warned by a Shamballah king not to engage in animal sacrifice, lest they would be undistinguishable from such bloodthirsty barbarians.
And who are such cruel animal-sacrificing barbarians? According to the Kalachakra Tantra itself, none other than the followers of the eight prophets of the assuras and of the nagas, to wit, Adam, Noah, Abraham, Moses, Jesus, Mani, Mohammed, and Mahdi. In a nutshell, the followers of the murderous Abrahamic ideologies of Judaism, Christianity, and Islam.
