I'm not acting morally superior. I am morally superior
Do you use feet? Do you use your hands?The point of having these is to help is survive.
It's not the gun that kills people. It's the idiot that uses the gun that kills people.
We have a gun, should I shoot everything in sight? Its meant to survive.
But is the gun a part of your body and not a by product of evolution?
Controversial statement here, but guns are not parts of our bodies evolved for specific purposes.
We use our body parts to use tools. Do you eat everything with just your bare hands?
Which is a by product of the evolution of hands. Hands were designed to make picking things up easier. Have you tried picking stuff up with just your mouth?
I managed to stop eating meat by my own choice at the age of 4 so I think you can exert that basic amount of self control as a teenager.
