I've heard some vegans say that, regardless of whether it'll be waste or not, consuming animal products reinforces the notion that animal products are for consumption. Like, if someone unjustly kills a person, it'd be hard to stomach eating their remains just to make sure their body can have use after their tragic death. It can be a difficult subject to navigate, but I personally wouldn't eat animal products even in the case of potential waste. I just can't bring myself to do it.

It's not your fault that the people around you aren't vegan and that they waste food. You're already doing well by being vegan. You can instead just try to not waste your own food!

Eh, I don't care much about ideological purity. I generally find animal products aversive, in a similar manner to that which I would find human bodies presented as food or tools aversive.

If you want to eat somebodies table scraps I don't think it counts much one way or the other, but I would be cautious about the message it sends to carnists who may interpret it as a secret desire.

Is there a mental disorder to explain the this need to not "waste" food? Like I don't know if I just hate leftovers, but always feel I have to eat everything "on my plate" So to speak. It makes it really hard to cook for myself. Maybe just something ADHD related?

can relate heavy, just compost what u can :(

maybe if you have space you could make like a separate "animal products" compost bed and use the compost from it to fertilize flowers or something? i think it's fine to "waste" food when the alternative is eating dead things or byproducts of industrial SA, but if you want to avoid waste anyways i think this could work. i suppose the ethics of this could be questionable, but I think if you avoid using it to grow produce and just use it as a simultaneous burial/enrichment of the local ecosystem it would be fine
