> The same way we look at ancient Greece philosophers thinking they had some pretty good ideas, a non trivial amount of people look at a century ago's society thinking some of it should be restored or expanded.
I think far more is that a few people want power, and they are adept at manipulating the 90% who follow a herd (and are far less informed than your theory seems to imply). The bad people sell a vision of power and contempt; not long ago many other leaders sold a vision of freedom, universal rights, opportunity, democracy, and fundamental equality.
Nobody sells the latter any more, seemingly dumbfounded by their opponents - Biden, unlike every president pre-Trump, seems silent on it and sells infrastructure legislation. Progressives now sell despair - they can't get enough of telling everyone how despairing they are.
Not seeing an alternative, people follow power and hate.
We are biologically the same as every human who has followed every cause; we didn't evolve biologically; we evolved culturally. Unless someone stands up for that culture - unless we do - then it's not hard to predict what will happen to it.
> I think it will fundamentally be a tough battle.
Every battle has been tough - really much tougher than the ones we face now. Imagine being an abolitionist or for women's rights in the early 19th century - that's a tough fight. Yet they fought, and eventually prevailed. Our only real foe is us - our predecessors developed all the tools we need, the public hasn't forgotten about freedom and human rights in the last 8 years; we just need to stop despairing and whining and get to work.
