"A grim joke, how do you get a flesh and blood creature to refuse to be transformed into an energy creature?"
"After turning into an energy creature, does that mean no more eating or drinking?"
"That's indeed a bit distressing, but many life forms' eating and drinking mechanisms are actually punishment mechanisms, not needing to eat or drink is actually a reward."
"So, what could make this universally hard to accept for living beings?"
"After transformation, regardless of your previous gender, you're destined to be gender fluid, neither male nor female, neither female nor male."
"...Isn't that the same as saying both male and female are okay? Wouldn't that be a reward for some folks?"
