We have to do it. Some of us have to do it in different ways. Doing small things where you can is all well and good but literally none of us are making a single impact in capitalism by making different choices about how we're forced to participate in it. Focus on tearing it down together rather than picking apart individual choices because those individual choices still result in participating in capitalism.
Going vegan can help you lose weight if you want to because you have to reevaluate all the food you eat so you can make healthier choices. But if you don't wanna lose weight, you're not going to.
I've lost plenty of weight without wanting to in the past.
Then how is this complaint about veganism? You've manufactured an unrelated excuse to continue doing animal cruelty.
i'm the direct opposite lol - going vegan hasn't made me lose weight at all.
