To be fair, a number of the men caught in those stings have learning disabilities/ very low IQs, and have basically been entrapped by the person posing as a child. And the really dangerous ones are far too savvy to get caught by Sue and Brian from paedohunteruk. I always feel the motivations of members of those groups are a bit questionable, like they seem to find the whole thing a bit too enjoyable.
My own view is that kind of thing should be left to the police, and we should just focus on our children's safety, and who we allow around them. The biggest danger to children is sadly from family/ family friends.
Just to add, I do agree that exposure to porn plays a huge part in all this. There are a lot of men now who are habitual watchers, addicts even, spending hours a day watching. I've heard of men watching it in toilets at work, on public transport even. It's all starting younger too. 30 years ago, teenage boys might get hold of a top shelf mag, or a bluey video which would then get passed around for a bit, but that wasn't a frequent occurrence. Now teenagers are watching it on their phones daily, and not just regular porn, but a lot of really dark, torture porn and worse. It really worries me
