I wholeheartedly agree - I have a friend who was raised solely by her father (after her mother died young) and she is a lovely and well adjusted woman... but it was less than ideal, particularly during the teen years. For her there were people who filled in a lot of the gaps.

I think it would be foolish to recommend raising the next generation of boys alone - because that's a choice. It's a political position rather than a necessity - and begins from a place of exclusion. To borrow your example, like excluding all the hammers from your toolbox but having everything else. Just because something can be done, doesn't mean it should be.

I think the ideal solution for any child is to be surrounded by loving adults of both sexes - there are other solutions which work, but they aren't the ideal solution. :o)
