Interesting. I still feel that peeing in pools is uncalled for. If you are old enough to control your bladder then go to the toilet, it is pretty ease just get out of the pool and walk to the nearest one. Are people getting that lazy that they feel it is ok to just vent their waste into a communal pool. Would you pee on your couch then sit in it just because you don't wish to walk to your bathroom? Or pee under the table in a restaurant because you are in the middle of dinner? Unlikely. So where is the ethical leap which states it suddenly becomes ok to pee in a swimming pool?

Regardless of what chemicals are in pools taking a pee in them is just unclean. Peeing in the bath would be unpleasant right, so would you do it? Most likely not.
