I don't actually think anyone
is justifying adults having sex with underage children.
What they are doing is acknowledging that it has happened, but failing to get into a tiz over it, instead preferring to have a reasonably sensible discussion about all the issues that arise about consent, using one's judgement, and the way in which attitudes have changed (somewhat) in 40 years.
I fully appreciate that some people are simply going to be so outraged by the whole thing that the limit of their thought on the matter will be "Bad. Shouldn't happen". That's fine. But for those who might want to explore the subject in a slightly more considered way, it's getting a bit tedious to keep batting the absolutists out of the way, or fend off constant accusations that even having a discussion about it is somehow justifying or excusing the initial behaviours.
We hear you. Your bullet point opinions (not just yours,
comrade spurski) are there for all to see. Just because they haven't brought the discussion to a screeching halt following by universal agreement of what you're saying doesn't mean you have to repeat them.
