That sounds pretty bigoted, IMO. You were a little one once too, what were your parents' attitude towards nudity and exposing you to it?
I agree with guyinaprince, it's not my responsibility to alter my entire life because somebody else decided to breed.
As to the episode that started the thread:
When I was 15, we had communal showers in school and nobody thought a thing about it.
I could understand this thread a little better if it were, say, a 5 year old or an 8 year old boy, but *15*?
15 is getting close to being an adult. 18 (3 years later) and he can be sent to Afghanistan!
The father was totally out of line.
I will also say: parents, it's YOUR responsibilty to worry about your kids, NOT MINE. That means, it's not unreasonable for me to want a quiet dinner in a nice restaurant without your brat screaming and throwing things. It's not unreasonable to expect me to be able to change my clothes and shower in the MEN'S LOCKER ROOM without your having a fit because your 15 year old son might see my penis! (The gym where I go prohibits children under 14, period. They have a daycare for kids, and a separate kids program, but no kids in the grown-up gym. This infuriated the parents, but was a huge relief for the rest of us).
It's not unreasonable for me to be able to expect that, when I show up at the gym, and there are 6 treadmills, 4 of which are occupied, that you keep your brats from crawling all over the remaining, supposedly open treadmills while you finish your workout (this happened to me BEFORE the gym banned kids, and that's one of the reasons). It IS unreasonable for you to drop a 10 year old kid off at the gym for 4 hours while you go shopping at the nearby mall, while he and his buddies run wild through the exercise and locker areas, getting into trouble.
Sorry, but that one touched a nerve. I have no objection at all to quiet, well-behaved children under adult supervision; I just see no reason why they are MY responsibility.
