We can all as women/girls definitely have a view on the results of the parenting of (some) boys. But I'd be more interested in the advice of a mother of boys who turned out OK.
Having older teens there's absolutely no way I'd know how to deal with a tricky 15 year old girl as they react differently to certain things to boys, but I have an idea how to deal with a 15 year old boy having had two that so far have evaded prison (touch wood).
Incidentally Adolescence however brilliant, is a story. The stats don't support a huge problem with white working class boys from stable families going round murdering girls.
