So, we need to get "back to the basics" you say. I'd say eating meat is "back to the basics", as well as eating it with veggies and fruits and other grains.
Back in the day, there was these two categories called "hunters and gatherers", of which I'm sure you are aware of? What do you think the hunters hunted, with sharp pointy spears? Tomatoes? Apples? Uh, no.
Why do we have canine teeth if we are only supposed to eat "veggies"?
At one point you were arguing that we shouldn't eat meat and then at another you switch to we shouldn't eat meat due to the morality of how the process is run. I'd say that if it was truly a moral issue, isn't killing, killing anyway you slice it? Either way it is immoral, unless you think certain types of killing are morally acceptable while others are not. Slicing a head off vs. jabbing a knife directly into the jugular both end in the same result.
