I think this is one of the saddest questions I ever read. I do not want to think about it. (I taught a class in a communist country that is/was slowly opening up and becoming more capitalist. They were/are also extending more freedoms. My class was entitled "The Right to Fail" )
Children especially need parents that routinely protect them from the consequences of their actions. Sounds strange to folks who just love the concept that enabling is wrong. The parent to be real must take the punishment for their child. Of course gradually allowing more consequence to fall upon the child.
My 3 year old does wrong things --- but he is never wrong. My 20+ year old does wrong things and she is wrong. But in both cases we suffer the consequences together as best we can.
But I ask all seriously; "In a parent child relationship who is the teacher and who is the student?" "If a parent thinks they are only a teacher. They are done growing and will teach their child that it is OK to stop learning and growing"
I do get angry. Mostly that would be on me not what an angel does. I am not perfect but I do not and cannot condone those who harm children with anger. "Tolerance should never be an issue between parent and child for if we must be tolerant then we have already judged to harshly".
With all that said, I am a hypocrite. For I will not tolerate whining. Fun subject and important for people to reflect on. Thank you for bringing it up. But that danged picture makes me nauseated! ;-)
