I even think the feeling of becoming a vegetarian because I feel so sorry is childish. But when you dig in, it's a lot complicated.
Rice also has gods and life... This feeling is common in polytheistic countries. In Japan, they are called Shinto's 8 million (yayorozu) gods. However, this feeling is difficult for monotheists to understand. We must know that there are people who don't understand it.
The feeling that dolphins and whales are smart and shouldn't be killed makes us think, “Huh? What are you saying?” It's like that. Why is the treatment different? The Bible is in the background. In the Old Testament, the first humans are banished from the Garden of Eden as punishment for eating the forbidden fruit of wisdom. This is a metaphor for people discovering the uniqueness of human society and understanding the natural world. Therefore, for Westerners, having wisdom is not just a pity, but may also be close to a sense of family.
Conversely, unlike animals in the natural world, livestock are beings given to humans as food by God, the creator. When listing living things, they list people, fish of the sea, birds of the sky, domestic animals, animals of the earth... Domestic animals and animals are the same, but they are separate. “Livestock is livestock, so it's natural to treat them like livestock, right? What are you saying do it with whales?” That's the feeling. It seems that plants and trees are also given by God as food for living things.
Of course, I don't think so because I'm aware of the Bible. However, as a culture composed of a religious backbone, as a folk feeling naturally inherited from parents and people around them, it somehow became an idea in that direction.
For our part, I understand the logic, but I'm not convinced at all. But it's just like each other. “Rice also has gods. Even flowers have life.” I was told, “Huh? What are you saying?” There are also people who aren't convinced.
So first, let's understand that “ego is something we tend to unknowingly impose.” We must try not to criticize other countries or cultures lightly.
Then, if possible, get to know the roots of my beliefs, and say, “Values rooted in Buddhism and Shinto are values rooted in Buddhism and Shinto that are not distinguished as much as possible. Let's be able to clearly explain, “It's a problem even if it interferes there.” The actual percentage of fanatical people isn't as high as rumored.
