&gt; <i>Especially eating it, which is in the natural order of things.</i><p>Yeah, those claws that you use to hunt your food down are pretty natural.<p>Appeal to nature is an argument flaw and if you are rational you shouldn&#x27;t use it.<p>Humans ate meat because they saved their energy. Do you know how they saved it? The non-human animals were walking around collecting nutrients so humans didn&#x27;t have to waste that time. These non-human animals were nutrient packed and it allowed humans to save time, have more offsprings and survive.<p>Today, there&#x27;s no energy savings. Today we bring the food to the animals, filtering millions of tons of nutrient filled grains through inefficient bodies that waste almost everything on keeping their temperature - their body warm. It is as far from nature as it gets.<p>You can&#x27;t say there&#x27;s something special about flesh that you need to survive, and there&#x27;s nothing else that has it.<p>You like the luxury of eating meat, you like the taste, you like the texture. It is a luxurious activity that you allow yourself to have, ignoring the effects on the environment, ignoring the suffering (and yes there is no such thing as humane murder, rape or slaughter), doing it just for your pleasure. And it recently turned out to be almost an equivalent to cigarette smoking - so it&#x27;s entirely irrational from a health perspective but that is the case for most of the luxuries.<p>That&#x27;s fine with me but don&#x27;t try to rationalize it, it is in its complete entirety - irrational.<p>It is also ironic that you pointed out a perfect example of speciesism (humans preferring one species over another) and you couldn&#x27;t label yourself as a speciesist. It is also ironic how you pointed out the irrationality in other people, not seeing your own when it was right in front of you.
