There is literally no need to rape women, but it feels so good that I won't stop raping them :p
Being a vegan isn't about not ever using products that exploited animals and hurt them, but rather minimizing it as much as possible.
You can easily control what you eat in modern society. You can't control what they use to create tires.
In the same way that 4 legged mammals have greater moral value than insects, worms, or rodents in your moral sphere, so do human women have greater moral value than 4 legged mammals in most folks moral sphere's.
That's because typically a 4legged animal is more developed and capable of processing what's going on than an insect or worm, at least as far as we can understand.
I'd kill 100 rats to save a cute babies life, but that doesn't make it right, but that's what I'd do.
However to kill 100 rats, or in the case of corpse-munchers, kill 50-100 animals a year simply because they want a momentary sensation of flesh and the knowledge that it's "real meat" is not just immoral, but inexcusable. It's senseless. It's not to save another more valuable (subjective) organism, no, it's just depravity.
Hopefully you would kill 100 rats whether the baby was cute or not.
