That was just a joke but in seriousness, telling people they're being crazy or hostile or paranoid or too sensitive is NORMAL SOCIALIZATION and letting yourself be held hostage to the most extreme person in the room claiming victimhood is enabling and normalizing pathological behavior. Which is bad. Don't do that. If someone puts themselves out there and is met with pushback for having insane ideas, that is the correct response, not sheltering their fragile and underdeveloped emotional responses.
