, we are omnivores. Our digestive system handles both plant and animal matter. It's not like most people are just killing animals out of spite. The fact that we can choose to abstain from eating animals and still function properly is a nice side effect of that, but eating meat isn't "wrong."
There are no moral quandaries to eating meat, only ethical ones, and the ethics I do see as part of the problem pertain more to waste and abuse than the act of consuming animal flesh.
