Why do you care so much anyway? Why can't you just ignore them?
That's a fair question.
First, let me reiterate that I do know that real and profoundly disabling trauma exists, often in the form of sexual abuse or violence. That - and the need for proper psychiatric/therapeutic care - is not up for debate in this thread.
Why am I interested? Firstly, again, I was intrigued by the study described in the OP. It was not what I expected to hear.
I care because I perceive our society to be pathologising everything. Medicating everything. And that young people (whose welfare I care about) perceive themselves to be far more fragile than they really are. And for people to go through life perceiving themselves as fragile is a dangerous and unsustainable situation. This comes from years of experience in interacting with young people (in personal and professional ways), as well as the simple observation of the wider culture.
I think there's a blame culture, and that young people increasingly look to some sort of authority figure to help them manage their difficult feelings. This is borne out in university contexts, where academics are accused of hurting their students if their work is criticised. To the point where medical students may not have been robustly examined, for fear that the profs get accused of something. So that system is producing second rate doctors, or (more widely) second rate critical thinkers.
It intersects with the 'woke' issue because at the heart of that is the critical social justice movement, which reduces everyone down to oppressed/oppressor, and in order to avoid being 'oppressor' people need to find themselves an aspect of victimhood. Straight white men are the most reviled. Middle class straight white girls or women are second in line.
Going through life thinking in terms of grievances and micro-aggressions is reducing our culture's robustness. It is highly divisive. It is churning out people who are medically damaged or reliant on antidepressants. It's a culture full of people hopelessly reliant on the opinion of others. It is profoundly unhealthy. Which is surely borne out in the staggeringly depressing stats around young people's mental health.
So I would argue that we should not be coddling young people. I think, given the challenges ahead, we need stronger people. And I am interested in how that can be encouraged.
