Systemic failures - coming from both deliberate infiltration and the deliberate seeking of like-minds, and then the appeal of a situation to those who 'unwittingly' (for want of a better word) seek to normalise their unhealthy behaviours/ mind sets and are drawn to permissive/ encouraging environments and then the two collude.
Sightly off-topic but just clicked on that Krysty's twitter and this caught my eye.."Don't let anybody else's opinions or views control your actions. Do whatever makes you happy." as supposedly said by a young girl speaking about mental health. Now its one of those sound bites where you kind of you see where she is coming from, say if someone was a victim of bullying, but as a 'rule' to follow, its pretty terrible.. but actually I think that this simplistic sound bite type stuff is what is sticking.. it is lacking the nuance, the spectrum, the complexity - it combats doubts and lack of self esteem with blind and simplistic self-justification and of course is easily followed by "if it makes your happy its your right" and "who is anyone else to tell you No" and "acceptance without exception" 
its like that thread that linked to research on the brains of extremists that found that extremists's brains switched off areas used in critical thinking when they talked about their extreme views and instead used areas associated with belief. I think there is a huge danger that kids (and adults) are being taught (and have for a long time) to use 'positive thinking' = irrational optimism to combat doubts rather than develop thinking skills and robust sense of self that can think critically and take and reflect upon criticism, be truly resilient etc and its getting worse.
and so that "it'll all be OK, sweep it under the carpet, magical thinking mentality is part of what allows this neo-liberal, irrational anti-safeguarding culture to flourish.. We use to have "just say NO" and wise sayings (pleas insert here), but now we have "just believe kids, just believe" and "anything is possible when you try hard enough" and all that other (obvious) bullshit. The cultishness of all of this (verging on mass delusion?) is worrying and its been going on for decades, slowly ramping up.
I have had a hard time personally butting up against people's irrational optimism and refusal to acknowledge the (objectively verifiable) seriousness of a RL situation and really its the worst kind of feeling, and quite scary.. mass denial/gaslighting - some knowing, some unwitting, many polarised views, few able to see the middle ground reality, as per general politics now The world had gone nuts... if it wasn't already.
What we are seeing is the tip of the iceberg. its just all so pervasive
