“They don’t mind killing Plants”
Plants, like embryos, cannot convey pain or emotions.
Some Vegans and Hippies would dispute that.
The point is vegans are killing something to eat just like animals killing other animals to eat. Something alive dies to feed something else alive. Embryos die because of selfish desires. Besides, what does one’s ability to convey pain have to do with anything? I can think of plenty of scenarios where pain could not be conveyed, but real. Inflicting pain is A-ok as long as the object of pain can’t convey it?
