It's true that some vegans can be overly vocal about their dietary choices, but it's important to remember that veganism isn't just about making a personal preference - it's about taking a moral stance that has a real impact on the environment. It's true that if a few people convert to veganism their impact will be multiplied, but it's not just about converting others - it's about creating awareness and advocating for the ethical treatment of animals and the environment. Veganism isn't multi-level marketing - it's about making a positive impact on the world. UrRong in suggesting that veganism is just a personal preference - it's so much more than that.
