Defenses work best when they are relatively unconscious. The more conscious a defense is, the less well it works.
That’s why people get upset when you talk psychology. “Enough psychobabble!” These are usually extroverted Normies, usually men who are not too young. They are dealing with life by simply refusing to look inside of themselves and denying everything that is unpleasant down there. When you even mention the word psychology, you remind them of how fake their happiness and adjustment is and how it’s all based on mass forgetting and refusing to look at a whole lot of things inside of themselves. You remind them that there’s a creepy closet in their psyche full of all sorts of scary monsters who they are too scared to even look at, hence they are acting like scared little 7 year old boys.
A lot of people also think “depression is evil.” They think people choose to be miserable and by choosing this, they are making an immoral choice. They are sort of like criminals. They’re bad people! That’s a Hell of a way to feel about depressed people like that, but it’s not uncommon. Usually seen in a professional person of either sex aged ~30-40.
After 40, you’ve seen so much depression and probably experienced enough of your own that it’s hard to call depressed people evil anymore. It hits too close to home. Also, by 40, almost everyone has had about a million bad things happen to them, and most people simply don’t think that their shit doesn’t stink anymore. There is a humility that comes with middle age, even to the most arrogant people. The weight of time and life humbles us all.
