Exactly.
Hitler is a great example and one I wouldn't have thought of. Unfinished business is not uncommon but it should be.
All of these things should be taught to your kids when growing up and then it wouldn't be such a struggle to do it when they are older. I understand circumstances prevent it, especially nowadays with people having children they aren't even raising. It isn't the schools' responsibility to do these things, but, that is another whole post.
I'm not a parent so try not to comment much on things like this, but it's really a pretty serious issue. Also, I see (perceive) that many parents just aren't equipped to do the child-raising as they were raised incorrectly themselves...I don't think schools are the right place for this raising scenario either; agendas and all.
I was just having this exact discussion about a week ago. We are two generations deep with unskilled parenting. How sad is that? It's more of a problem than people realize.
Yeah, I think humans have got very good at denial and avoidance. Sad indeed, because this particular scenario is spiralling out if control and won't end in a good place.
