Rehab programmes do exist for this sort of thing. You are making a straw man here.
Not seen this show, but there is a definite feel of entrapment about To Catch a Predator, which I assume this is basically the UK counterpart of. If a TV show is making you feel pity for a pederast, you know it's a bad thing.
I don't think I am.
Rehab programmes exist for everything. The point is, as a society, we've reached a stage where we can sympathise with suffers of PTSD, schizophrenia, dementia, and even with psychopaths (to the point we are comfortable having them as protagonists for our television shows)....but a pedophile still carries a huge black mark.
If you are a Pedophile, you must be an awful human being.
If you are a Pedophile, you must be a threat to society.
Entrapment is wrong, but it's okay if you use it to catch a pedophile.
It's not the right way to go about it, IMO. Stigmatising pedophiles and tossing them in jail for consuming child porn isn't a sustainable way to stop that vile industry.
Instead, if we as a society encouraged those who felt this way to come out and seek help ASAP, and made them feel safe and not like some sort of monster, then we can get them the help they need. What we have now, is that we've got youngsters who are realising that they have these desires, and instead of being open about them, they hide them, because confessing to finding young kids sexually attractive brings upon them a whole word of hate and shame that they don't want to face. Good help, and sympathetic therapists, are fare and few.
So naturally as a result these closeted pedohlies try their best to satisfy their urges however they can, instead of getting help to get rid of them. And that's how you end up with the white collar middle class man with 2 kids in the house down the street with the nice job suddenly being hauled away for have 200 gigs of child porn hidden in a computer in the basement.
I understand regressing pedophiles are a whole other issue, and generally the type of people who slip into it are the ones who will claim they aren't pedophiles. In their case entrapment is probably the only way to catch them out. But then to broadcast that entrapment to the public, make a big scene out of it, embarrass the people who are caught...how are you going to get people to admit they are pedophiles and look to seek help this way?
Stop hating on pedophiles. Encourage them instead to come out and seek help ASAP. Treat it like you would depression or any other mental illness. Help them cure their desires. Thus reduce the demand for kiddy porn. Thus save more young kids from that horrible experience.
