Productive criticism is necessary to any civilization, it helps prevent gradual social devolution, which is exactly what this is. People are waaaaaaaay too comfortable making their childhood issues everyone's business because some 'think' no one will say anything.
Which explains the desperate defense mechanisms & deflection whenever someone does say something, pure fragility born of a culture of weakness that spawned from a culture in decline.
Dysfunction breeding insecurity and dysfunction. As it tends to do.
