Janet’s explanation is pretty much my reasoning.
A parallel is my vegetarianism. I don’t eat meat, and I don’t go for veg-based things that try really hard to be meatlike. But a patty that is openly made from black beans? A miso soup that doesn’t pretend to be beef bullion? Stir-fries with tofu chunks that no one would mistake for chicken? Bring them on!
I don’t see the hood on my vest, these scarves, or my black shrug as trying to pass themselves off as actual fur, so I’m all for them—much more than if they “tried” to be something they’re not.
