No offense, but your post makes it sound like might have missed the point of the article. This isn't about "converting" kids to anything. (In fact, thankfully, the kids in this case seem totally oblivious to the role they're playing here.)
The issue is that a few jerkwads are sneakily tricking kids into saying -- or sometimes acting out -- things that titillate the jerkwads' sexual fantasies. It's troubling because someone is using kids as unwitting pawns in a sex game.
If we agree on the point of the article, then comparing it to "gay sex" -- which exploits no one, let alone children -- is, frankly, offensive.
