I believe the situation is similar for harms to others. Acts that make you a non-Muslim are a much narrower set compared to sinful actions. A thief still remains a Muslim/​Christian/​Jew as far as I know. Even murderers are still considered as believers depending on the denomination.
That seems to be true, you’re right. In that case, maybe the difference is that a vegan is defined by their refusal to consume animal products. If a vegan does consume animal products, they are no longer vegan, as they no longer fit the definition. A Muslim, a Christian, or a Jew is not defined by their refusal to harm others (based on what you have said). Someone can be a murderer and a Christian; they might be a bad Christian, but still a Christian. You can’t really be a bad vegan by eating animals—you just wouldn’t be a vegan anymore. I’m thinking out loud so I don’t know if my point is clear, but it feels like vegans are necessarily defined by refusing to consume animal products.

I agree!
