Parents in Manchester have complained about naked swimming, claiming that it's unhygienic (though it's obvious that the complaint is really just motivated by prudery).
The naked swimming is taking place in a private, closed session in a public pool (so no-one actually sees the naked people in public). The group concerned book the swimming pool of an evening.
Parents have complained that their children subsequently have to swim in the same pool. Well, as various commenters on the story have pointed out, swimming trunks are not an impermeable membrane - people's naked tackle is touched by the communal water when they've got swimming trunks on as well. Besides, that's what chlorine is for.
It's just a small-minded response to the idea of nudity. Though I wonder if the fact that the naked swimming group also happens to consist of gay men might have something to do with it.
