We were in a comfy peaceful era and yet we saw rise of extremism, neo nazis in germany, in the US even. Good times allow for forgetting the extent of what reality can be and then people start to have weird ideas when small problems come, only to react in shallow reflexes like nationalism, and war.

I may be dumb but I assumed people who saw wars just didn't want any of that anymore and would actually know what 'right value' means, not just school books or worse .. network propaganda.

Now sure, it can all be twisted, people can be brainwashed during and after war, there can be bad wounds for long too.
