Young people have always had that mix of over-confidence in their own opinions and blindness to subtlety - both about the situation itself and about the consequences of actions.
We all want to protect the vulnerable. But we oldies can see that a 40 year old accountant who gets off on wearing women's clothes is far less vulnerable than a 13 year old girl with ASD who has experienced CSA. And we can see that a policy of instant affirmation will benefit the Accountant (who gets people propping up his fantasy) whilst causing huge damage to the girl (who seeks hormone blockers then cross sex hormones as a reaction to her social difficulties from ASD and her desire to get away from the constant male gaze - then ends up with no sexual function, a hysterectomy at 25 and osteoporosis at 40). We recognise that once again the vulnerable girl is collateral damage to benefit the powerful male, and we can conclude that this is not a progressive social change. In fact, the opposite.
I think we develop more subtle understanding by repeatedly seeing things turn out in unexpected ways. By misunderstanding things - being wrong ourselves - and realising months or years later. Lots of times! But it takes decades of life to experience that, and (if we are thoughtful) develop more humility and a more subtle understanding.
The problem is how much power this generation have at such a young age. Mao's little red guards are a good comparison. With technology, this generation likewise have the power to destroy people's lives.
The cultural revolution ended when Mao died. But technology isn't going back in the box - and we wouldn't want it to, because it brings huge benefits. We do need to find a way to control it. Personally, I think it will be with a whole raft of new laws. But that will take hard work over many years to figure out.
