Your understanding of history is obviously very shallow and comparing military personnel to 17 year old dancers is quite a stretch.
No, not really.
There's plenty of more damning stories to post if that was my intent. I'm wondering why the hell would anyone willfully wear diapers for the image of something like an Olympic ceremony? Someone answer the question.
Why the fuck not? It's not like they're making you suck a row of cocks or drink a gallon of piss. It's an adult diaper. Hundreds of thousands of people wear them. Maybe I'm alone, but it just doesn't seem like that big of a fucking deal. Why would they do it? For the same reason they wanted to participate in the ceremony in the first place - why else?
The question doesn't fucking need to be answered! It's like asking "why the fuck would anybody willfully put on a costume just for the image of something like a parade"? Your question only makes sense in the way you want it to if you are holding an assumption that all people do or should have an amazingly powerful aversion to wearing diapers, which I don't really have (okay it's unpleasant, but I'd hypothetically have a chance to take place in a historic event and if that causes me to be somewhat inconvenienced, fuck that), and to me it seems like just not that much of a big fucking deal.
