It is the very definition of insane. That doesn't mean we shouldn't have sympathy for it, but it's important to recognise when certain aspects of our psyche isn't sane or good and accept that.
I never meant to claim it's good or sane that I want an animal body, but it's something I can't really help. I don't have the delusion that it's ever actually going to happen, I just can't help but wish that it would.
