are vegetarians more ethical by not eating meat?

[NoraBrimstone]

Category error, we're not talking about the physical capacity to kill animals, we're talking about its moral justification or lack thereof. This kind of reasoning has been repeatedly refuted, even within this very thread.

Let me illustrate the fallacy: Men are often physically stronger than women. From your logic above it would follow that men are not acting immorally if they rape women because they have the biological capacity to.

I believe that's what a scientist would call bullshit.

Now there's a false anaolgy if ever there was one. Rape=harmful. Meat=harmless.
