There are no nonvegetarians who don't feel some guilt, even if only momentarily, for their love of meat. Just about 30 minutes ago, while I was driving, I asked myself, "have I eaten babies?". The answer, to my dismay, is "yes"; I've eaten lamb and eggs. I'm sure I'm not the only one who's had this realization at some point in their lives. Believe me you, it's not a pleasant experience. Given how frequently and intensely reality assaults our sensibilities, we get used to all the pain and suffering that's around - desensitized, we think nothing of eating babies; ok animals, still babies.
Ethics, the issue at the heart of veganism/vegetarianism/non-vegetarianism, is, for me, one of the many ways humans have exposed nature's deep flaws - it's red in tooth and claw, carnivory is essential for a balanced ecosystem, and so on - but we've begun to doubt that logic for a long time and things are coming to a head. This is not, as Leibniz believed, the best of all possible worlds! We can do better! Is this bad/good? Is veganism/vegetarianism a hindrance/help? 🤔
