there is a good argument for both sides, people say eating meat is natural, because we are naturally meat eaters, its out instinct. some people say that its instinct for animals, but us being humans, we can make that choice, its not our instinct any more, its something we can control and we dont need it to survive.
personally i see a good argument on both sides, but really i dont care enough, i dont eat alot of meat just cause i like other stuff more, but i have no problem eating a burger or whatever every now and then.
this is my poorly thought out argument, plants are living organisms, like animals and humans, with plants being the least intelegent, plants really are pretty cofusing, some can adapt for different weather, protect themselves from predators, shit some are even meat eaters like the venus fly trap. then there are animals with different levels of intelegence, its hard to tell if animals have emotion, or if its just instinct. then we get to humans, we have emotions, love, are extremely smart etc... the point is, we are all living organisms, and we are all edible.
so really vegitarians are eating what used to be a living organism, just an organism with no ability to really think, meat eaters are eating organisms that are still very dumb and dont have emotion, but have instinct.
so if i had to give my opinion, the smarter the organism the worse it is, i could care less if someone eats something that can live without a head (chicken) animals like that are dumb as shit, the only thing that makes them resist dying is instinct, even plants can defend themselves, so really i dont care. but if its something like a dolphin, elephant, dog or something much smarter, which might have some kind of emotions, then i start to think its a little cruel.
