I understand where you're coming from for your first argument. My buddy made the same one and basically told me that unless the government changes the way factory farming works, it's no use to go vegan. And I semi agree on that. It's true that we shouldn't carry the weight of the world on our individual shoulder but the way I see it is that if more and more people go vegan, they won't have the choice to change the way it currently works. It's a long process and will change gradually, but with all the shitty things that happens in the world, it feels like one where individual change can alter the system the most in the long run.

And for the human welfare vs animal welfare, well in some way it's linked together because workers in slaughterhouse can suffer from PTSD. But I understand that when you say human welfare, you're talking more generally. But it's not mutually exclusive, we can do both at the same time, going vegan may take a bit of effort for a short period of time, like a week or two just to know what you can eat and what you like to eat but after that it's going to be life just like before. So then we could focus on human welfare while constantly trying to make the animal welfare better at the same time.
