People tend to laugh at this, and I don't really see what's funny. I feel like once you know the facts of your existence, you are logically obligated to not eat meat or dairy/perpetuate suffering you know is happening. In basically the same way you wouldn't yourself want to be farmed, tortured, live a miserable life, and have a miserable death. Vegans cause less harm, that's just how it is. Life arose in a cesspit billions of years ago and has been evolving ever since with no intelligence or any compassion for sentient life whatsoever. Life is imposed, so you have no choice in playing the game, you just suddenly arrive on planet Earth. We grow up seeing nature at work, and some people think it's beautiful, which is strange because we all know the miseries that happen to sentient creatures every second. Most of which we can nothing about, but the bit we can do something about though (because we're smart) is the harm that we cause. I am utterly ashamed when I think of all the meat I've eaten and how unquestioning and selfish I was. In what world, when there is plenty of stuff to eat, (and no, I am not having it that a lettuce has the capacity to feel pain like animal does) does it make any sense to exploit others? Would beings more intelligent than ourselves cause needless suffering? I don't think so. Can someone rationally justify themselves eating meat? Or are you forced to admit that you are just an ignorant/selfish person?
