That's because most livestock is bred specifically to be eaten. If no one ate meat, those animals wouldn't even have lived. In fact, many species wouldn't even be around right now if they weren't meant to be eaten or used.
Would you accept it if someone
specifically bred certain number of dogs just for killing? One could also say that those specific set of dogs wouldn't have been on earth if not for that one guy who decided to breed them (although only for killing)
