The point to me is that there are various forums for expression within society.
A crowded theatre is one of them, with a particular expected audience, and the commercial success of the theatre is dependant on pleasing that audience.
Clearly no one would ban the shouting of "fire" in a theatre - the right to do so is inherant in health and safety. If one does shout "fire" they should be prepared for the consequences for such anti-social behaviour - such as being barred from the premises.
Obviously the consequences for saying that you think age of consent and statutory rape laws ought to be abolished is that people will widely take a dislike to you and suspect you of all manner of horrible crimes. To the extent that they want to see you punished for murder just because a murderer happened to own some of your literature - apparently. This is the risk that such individuals no doubt face - the risk of ostracising themselves from society at large. That's their due I suppose, I'm not arguing anyone like what they say.
However, what the state should still offer to ostracised groups - whilst it can't (and shouldn't in this case) simply order people to like them - is the same basic human rights as people who haven't ostracised themselves. This way social ostracism needn't become some sort of state-sponsored untermenschen thing, where someone who admits to finding minors sexually exciting would end up being tried for murder - their only crime being the admission.
"First they came for the pedophiles - and I didn't speak up, because I wasn't a pedophile..."
Which is all well and good if you hate such people, and I admit they are a very hard group to have any sympathy for given the horror the crimes some of them do commit provoke in people.
This is not a dainty world - bad things happen. People talk about doing bad things a lot more than they actually do them though. Sometimes talking about bad things vents the anger and frustration, sometimes it stokes it. In the UK the neuroses about pedophilia probably prevents an equivalent of NAMBLA being tabled - who would have the nerve? Because of the fear associated with even being tempted by the idea - regularly fed by our red top press - anyone attracted to children and seeking to talk about their sexuality here would have to do it surrepticiously, where they will
be offered child pornography and will
come in to contact with practising pedophiles.
You know, actual
crimes rather than just thoughtcrimes.
And what next? Shall we suppress all expression of drunken violence? A problem that marrs far more lives than child abuse. Let's not talk about it and the problem will probably go away...
Not a dainty world, and wrapping things up in cotton wool does not make for a good suit of armour.
