I'll have you know it's perfectly unnatural when I invert my corporeal form to assimilate my terrified victims into the eldritch void where my soul used to be.

But in all seriousness, agreed. It's not possible for something that's part of nature to be unnatural. All behaviors are natural. Some behaviors pose a threat to the individual or society at large, and that's the only case where any action should be considered, but only as a harm reduction strategy rather than punitive. An individual's sexuality, gender identity, etc., definitely don't qualify as dangerous.
