I can understand if you follow a religion where the religion says not to eat a certain animal because it's sacred, but it seems that there's lots of non-religious negative reactions to certain animals being eaten.
For example, a lot of Americans find it morally wrong to eat a dog. Sure, I can see how you might see someone eating dogmeat and remember your own pet that you love as a family member, but what if someone walked up to you while you were having a pork chop and told you they have a pet pig that they love as much as you love your dog? Should you feel bad about eating pork because someone else has a pet of the same species?
