Look, the fact of the matter is, children are sexual. Freud went on at length about the sexuality of children. A child's sexuality is a very natural, very healthy, very well documented thing. From admitting children are sexual to permissiveness of being sexual with children is a quantum leap. The one does not follow from the other.
A child's sexuality is not a mature sexuality. If a little girl gets a crush on a little boy, the most she probably thinks about is holding hands. But you can glean from this that, as an adult, her preference will be to fuck men and not women. It's a budding sexuality, that desire to hold hands.
But a child's sexuality can be far more overt than that. A parent's inablitly to deal with that is what makes people sexually repressed as adults. The child will think their sexuality is shameful. Or, they may try to hide it and end up exploring their sexuality in very dangerous ways.
I just don't think there is anything productive or positive about trying to force everybody to be quiet because you are out there watching the conversation with white knuckles.
If you have some deep, personal issue with this topic, you should take Granite_II's advice and stay out of it.
And, yes, I invented a childhood game called 'torture chamber'. It was always my first pick of what we should play. I wonder sometimes if those kids I grew up with think back on that and wonder if I'm into BDSM, now.
