I grew up in the 1960s. The adults around me had been through WW2, many had lost friends and relatives, had near misses or had been through 11 weeks of bombing night, after night, after night. Many had body parts missing. Many behaved very strangely at times. I would think a large proportion were suffering from what today we would term PTSD. But they just had to cope as best they could. Odd behaviour, such as sudden crying, shouting, abruptly leaving a room, etc was met with understanding shrugs and possibly people mouthing 'the War' to each other.
Today, for most people, life is generally comparatively safe, yet, as demonstrated on this very thread, we are encouraged to concern ourselves with the mental health of others. Anxiety is now a disorder, rather than a common negative part of the human experience. Being upset by a distressing life event is considered traumatic, requiring treatment, rather than normal, requiring sympathy and support to fight through it. We are discouraged from saying anything that might be 'triggering' or 'insensitive', even if there is no particular reason to think it would be to any but the tiniest fraction of the population, if at all.
I can't blame young people, but I do wonder at some of the parenting ideas I see on here. To me, a worrying number of parents won't give children from mid-primary-age upwards the chance to take on a little responsibility: perhaps a trip to a nearby shop, keeping an eye on a younger sibling for up to half an hour while the parent pops out, beginning to go to school alone, or wait unsupervised in the playground before school. There's so much 'what if something happened?', which to me is the point - the child learns to handle that vague idea, or to think about what s/he would do if 'something' did happen, with trusted adults only minutes away.
I'm saddened at how many young people seem to find it hard to express their needs and fight their own corner. I was shocked by the picture of Harvey Weinstein with his arm around a young lady; she appeared to be happily laughing into his face, but it turned out she was hating the situation. Why had her mother not taught her to say 'keep your hands to yourself, you creep'? (Unless she had decided that she would go through with what he wanted in order to get a job, which is a deal she could choose if she wanted; but I would prefer it to be her positive choice, not just a 'daren't refuse' situation.)
I'm not thinking of abuse of vulnerable children, but we should be teaching our adult daughters - and sons - to speak out loudly when someone invades their space/touches them inappropriately/expects unreasonable favours from them. We should be encouraging them to fight through the anxiety that naturally arises in order to stand up to bullies and bad behaviour, to loudly and publicly complain to those around, or an authority figure if available. (Not that they should have to, of course, but the world is far from as it should be.)
Each time we push ourselves out of our comfort zone, we get stronger and braver and find it easier next time. And, as parents, we need to let our children move outside their comfort zones, eg cope with the school's reaction when they've forgotten something important, rather than have Mummy run to their rescue, or spend a little time alone, albeit in a familiar place. And gradually build on that as they get older.
