> Sound and rational means peer reviewed paper

"My doctor has told me I should not take in as much potassium as I have been so I am reducing my consumption of legumes" and "I have an ethical objection to killing sentient creatures so I restrict my diet in ways that minimize such killing"

Are both sound, rational judgements which do not require a peer reviewed paper.

>You(sic) vegan foodstuff also require the killing of sentient creatures - to grow food we have displaced a lot of animals from their habitats. Sometimes quite forcefully. So yeah - you probably have fewer animals on your conscience , but you have some.

I agree with you, completely - it is an uphill battle. It is very difficult to not directly compensate the killing of creatures in a world that considers it moral to kill 50+ billion animals every year (not including marine life) - but my ethics require that I at least try.

That is rational, also requires peered review paper somewhere in the chain. The doctor read it and formulated advice based on it. Or at least that is the way medicine works. I hope.

But is having ethical objection to killing rational itself? We become what we are as being the better killers. Anytime, anywhere?
