Disagree with someone who holds an ethical stance against eating meat and explain that it is natural for humans to eat meat.
Your particular dietary perversity doesn't translate into any sort of valid moral standard, so I don't take delusions of "superiority" seriously in that regard.  It's no more "evil" for an omnivorous human to eat meat than it is for an omnivorous bear to eat meat.  For most of our existence we were obligatory omnivores, as the majority of our species found that preferable to starvation.  But tell you what--I live in Alaska, the "other" extra-limital state.  You can test my theory for yourself.  Visit Alaska.  Approach the first big brown bear you see, and lecture it on the moral and spiritual superiority of eating plants instead of ripping the roe out of poor mama salmon, or bringing down one of those cute lil moosies for dinner.  Be advised Mr. bear may express his disagreement by way of vigorous action on your person, up to and including killing and eating you.  Natural selection is always on the lookout for the weak and stupid.  It'll cure all your ills.
