Re " young men from 11-19", which if you think about it, is pretty much the demographic of Wikimedia's admins and functionaries." That's an old joke, but nowadays a joke that looks a tad out of touch. Yes a significant proportion of people were that age when they became admins in 2004-2008. But if there is one thing we know about the people who became admins ten years ago, it is that they are ten years older today. I couldn't guarantee that none of our current admins were that young now, but I'd be surprised if more than one or two were. Only twenty of our current admins created their accounts in the last six years. RFA has been difficult for teenagers to pass for several years now, If any have got through in the last six years they have been unusually mature in behaviour. As for Functionaries, Functionaries other than crats have to prove they are 18 or over when they become Functionaries. So it is theoretically possible that any new functionaries who first became so in the last two years could be 18 or 19, but it isn't exactly likely.
The template bombers who tag lots of articles for admins to delete probably do include some people in that age group, but admins? If 1% of the 1200 admins on English Wikipedia were still under 21 I would be stunned. Far more admins are over 60 than could possibly be 11-19.
