It is indeed wise to remind us, or any other group of people, that they can have their share of confirmation bias, logical fallacies, etc. And yes, we should always be mindful of it, of course.
That said, I think that I, along with Paedestrian and Gatekeeper (and others in that thread), provided a good degree of evidence that while we cannot know anything for sure about that case, it hardly seemed like a situation where the girl was being forced to have relations with that man if she met up with him in a hotel on multiple occasions, and he tried contacting her many years later on Facebook. I noted that it was certainly possible that she was subject to threats or blackmail to get her complicity, but it wasn't likely considering the factors I mentioned. So I'm not sure that was the best possible situation of that type for Andrew to give a devil's advocate style challenge to. And I did note that this was the only time he did that so far, and he has shown no sign of making a habit of it at this point.
I would also like to mention that the great majority of us fully recognize that genuine abuse of minors does indeed happen. There are many likely cases I have seen mentioned where force or coercion were used, and others where force and coercion were definitely the case. But most of the time (though not always), these cases of genuine force or coercion follow specific patterns, and underagers who frequently have return engagements with an adult who is not related to them and has no direct form of power or authority over them are not often good "candidates" for being victims of genuinely abusive, non-consensual sexual interactions with adults. Common patterns that do likely suggest lack of consent on the part of the
younger person are those in which the underager is under the direct authority of the older person, and is forced to spend time with them on a regular (if not constant) basis regardless of whether or not they wanted to. Note that I also pointed out that what he did was illegal, and he knew the risk he was taking, even though like you, I do not feel he deserved to go to jail simply for doing something that was very unwise.
As I said, Andrew has to be given some slack for being new to his regular interactions with us, and I am one of his supporters. However, he does need to consider how sensitive we can understandably be about certain things, so the approach he takes in his critiques is one of the things he needs to learn, and I'm hopeful that he will. If I can tell friends like Gatekeeper and BB in no uncertain terms when they do something that makes me cringe, then it's only fair I do the same with Andrew despite my support of him. But since he is new at this, we have to expect him to make a few tactical errors in his approach with us during his early days here.
