Jothar,
Good, thoughtful post.
One point- Everyone has their own baggage, and no one knows what is behind another’s door. So I wouldn’t judge an “adult who seemingly should know better” either. The “holier than thou” attitude, whether coming from the right or left such as cantoresq is most often a personal reflection on the individual’s history rather than a systemic phenomenon of the left or right, and should be received with sympathy.
