…are you implying that mass gas chambers aren’t an effective way to kill people?

The way I see it, it’s just a form of therapy. People don’t walk in and sit silently, they talk about their problems and get vague reassurance that everything is going to be alright - or occasional advice when they’re way out of bounds

I don’t think it’s unethical to do that, so long as you operate in good faith with good intentions

Stomachs aren’t necessary… You can jump straight to the large intestine. Even humans can survive like that

Obviously, they’re useful. It’s another stage of digestion, which means more energy and nutrients are extracted from your food. It widens your viable food sources, just like chewing does
