I was watching "A Charlie Brown Christmas" the other day, and Lucy (who has a running gag in Peanuts of being a terrible, or at least questionable, psychologist) tells Charlie Brown to get over his seasonal depression he should get involved in a Christmas project, and suggests he be the director of their play.
Which is to say, your stance might not be as controversial as you think, since it was the adult take in a children's cartoon almost 60 years ago.
Your Peanuts reference made me smile but I don't see why you thought a little girl's comment in a 1960s Christmas special was supposed to represent the "adult take" on mental health in the 1960s.
Lucy isn't actually a psychologist which is part of the reason the "gag" is funny.
