The ABA has a forum. This is not the type of thing discussed there, by and large (although I haven't looked at the feed for it regularly in a few years).
My point is actually that there that there should be space to discuss the morality/propriety of the actions, which upon your (E.'s) clarification is what is intended to be prohibited (and I strongly disagree with that approach); the legality of the situation was an example of something being discussed that may bear upon the issue of whether or not the actions are acceptable. While there are many legal things which are immoral (this will depend on what any given individual finds to be moral; remember that morality is subjective), and many illegal things which are not immoral (for example, other than someone who takes the view that all illegal things are immoral, few people would find driving one mile over the speed limit on an empty road to be immoral), that there is division about what the age of consent in different US jurisdictions is relevant to the baseline question of when is someone capable of making decisions regarding their sexuality, which is a subject relevant to John K's moral culpability. My argument is that that type of discussion, that defense of the accused, should not simply be banned, for the various reasons outlined previously. It is the role of those who find the behavior to be repugnant to explain why it is repugnant to those who do not find it to be so, not to tell them to shut up and go away.
As to the Jim Smith allegations, I would point out that these extremely vague allegations may be conflating the wrongness of a shirtless drunk with a man who was grooming middle schoolers for sex, and is an example of why it is important to have discussions about whether or not something is or is not wrong, and if wrong to what degree it is wrong.
