Yikes...I think you mean hakama, and students folding hakama for seniors is considered one way to learn to fold your own when you get one. Personally never got into that one (my teacher's wife usually folds his).
It's not like these guys took off their pants and proceded to strut around in their underwear while people ironed them for them.
Lighten up a bit...if the Japanese reigi is too much for you, perhaps Japanese arts aren't for you. Nothing wrong with that...move on.
