It has some unintended and bizarre implications.

Take the scenario of some guy who goes out dancing, having a great time with their preferred sexual partner on the dance floor. On the way home stops in the park for a wank because they're single, young, drunk, horny and stupid.

They get caught, they're on the sex offenders register and they're banned from working with children or vulnerable people. And yet they're not more of a threat than the average person, certainly not a paedophile.

(If that looks suspiciously specific, it's not my story 😁)
