Well, as long as you're acknowledging that the only practical reason to include nudity is immature shenanigans that may or may not fall under the pretense of "roleplaying", that's your prerogative. I was simply addressing the claim that "it's intent that makes nudity immature"; if there's no conceivable intent in using it that doesn't make it immature (offer one if you disagree) then I think it's safe to say that intent isn't the operative variable.
No, I won't acknowledge such a thing.
I can see many practical reasons to include nudity:
1. It's natural to be nude when you have no clothes on. Fact.
2. One would be able to examine wounds on your body, if there are any more permanent injuries on your character. Those wounds would be hidden from sight by your clothes. Maybe you'd even need to take, for example, your shirt off to apply salve or medicine to those wounds. Smearing them on clothers doesn't do much-
3. Earn an extra income as model for artists. Take off your clothes, let someone draw a beautiful painting, support art, get paid. Yay!
4. Using your very own "argument(s)" to bribe someone. "Will you let me past if I give you a peek?".
5. Swimming works much better when you don't wear panties that get soaked up by water (linen and wool do that alot) and become extremely heavy. The less clothing (and armour!), the better you can swim. Oh, and AFTER swimming is even worse, you'll most definitely catch a cold if you keep those wet pants on all night.
6. Back in the medieval periods, women wore only a dress as undergarment. No bra, no panties. Men wore pants, breeches to be exact. A bra, panties and corsage for woman have been excavated, but they are dated to the very late medieval period.
7. If you rob a person and take his clothes, why the heck would have any clothes left? What if YOU are robbed and left for dead by bandits? Believe they'd be so nice to leave you anything? I think not.
8. Immersion. What are those magic panties I can't take off? This is NOT the immersion a physics based world deserves.
Just because YOU don't see any practical reason to include nudity doesn't mean there isn't.
I'll go even further and claim if the only things a person can think about when they think nudity is immature shenanigans, that says alot about the person and their perception of nudity itself, and video games. If that offends you, I apologise in advance. My boldness is simply a fundamental part of my personality, and there is nothing I can do about it.
But I won't acknowledge the truth you have established only for yourself.
And I want to add that I'm in support of nudity for BOTH genders.
Treat them equally. Anything else would be silly.
