Many children will never know their dads.
Many children aren't allowed to see their dads because of child custody law.
Many children are brought up by single moms.
Many children have female teachers only.
This leads to children having zero male role models in their early lives (especially in their first 10 years), so they don't know what men are like or how they're supposed to behave when they grow up.
Isn't it kind of sad how men working with children is seen as creepy and potentially dangerous? Does nobody see the problem with young boys having no men to mentor them in their youth and show them how to properly grow up? Is it possible that men in childcare could even offer something that women couldn't? Nothing against female teachers, but analyzing the differences with children's behavior and teaching would be worth looking into.
