I agree there are apparently similar patterns among people who groom children for sexual abuse and men who groom partners to subsequently abuse them.
My issue with this article, and with the paedo discourse in principle, is that 'paedophile' is equated to 'sexual abuser of children' throughout the article. And that is simply not precise language. To top it off, the article ends with ''Mr Hennessy said that he has never encountered a man who wished to change his ways. "It’s a very sad thing but I've never met a man who came in and said I’ve behaved very badly and I want to stop," he said.'' Which, of course, courtesy the title, is then translated to all paedophiles.
This may not be a popular opinion, neither on here nor in general, but I have come to the conclusion that it is not helpful for society to conclude that paedophilic attaction equates acting on said attraction. There's a good documentary about it, which also features a paedophile who is dead set on not acting on this (he featues starting at 11:30 and at the end of the documentary, again). I think the message to these people needs to be: You have a choice, and whether you act or do not act on this makes a difference.
