...he is against identity politics and sees it as a danger for a functioning democracy as both sides, the left and the right has embraced this kind of politics. — ssu
They push for cohesion within their group but that can stand in varying levels of tension with the "shared public space" that is specifically kept free of the workings of any particular voluntary community. — Valentinus
The problem would seem to be the internet. The new shared public space without a stabilising "memory" to fix some sort of useful social goal in mind.
It is quite normal and indeed functional to have polarities or dichotomies. And the most productive divisions are those that are metaphysically complete - as in same vs different, competition vs co-operation, one vs many, integration vs differentiation, particular vs general. So a healthy society will be expressing some constructive balance of its tensions.
However, social discourse has changed in some essential way as it has moved from the old civics media age to the new social media age. As with everything, the internet disintermediates. It removes all the intermediaries that stand in the middle and "slowed things down". This removal of the middle ground can be free-ing. But it can also remove a lot of the machinery that represents some kind of collectively-adaptive memory. Sometimes things are being slowed down for good reason. Public institutions frame long-term truths and goals. They are designed to change slowly so that societies can be pointed towards long-term aims.
The social media internet strips out the kinds of checks and balances the old media had. Again, the old media had a lot of problems. It was in the pocket of the corporates and the states. On the other hand, governments and big business also represented institutional interests. They were part of the wisdom stabilising their societies in pursuit of relatively agreed long-term goals.
So the central question for me is about the nature of the internet as the new underpinning infrastructure of social discourse. Will it develop a sufficiently cohesive sense of purpose? Will it rise above the memes and hypes enough to develop far-sighted constraints?
The US might seem a hot mess for sure. But what is happening in India, or Ghana, or Chile? What does the new world order look like in terms of developing a modern institutional form?
I'm not assuming it is working, or not working. There sure is plenty of dysfunction any time you turn on the news. However that would seem the critical question. Trump and social justice warriors and all the other nonsense could be the true end of the old Enlightenment dream. Or it might be the noise masking the real deeper world social changes that will manifest.
Identity politics is clearly a symptom - but of what exactly?
Maybe the silliest part of Fukuyama's position would be the attempt to frame it still as a left vs right kind of thing. That feels so stale - the US dealing with its own "reds under the bed" existential threat. Or Europe still dealing with its industrial era class wars.
And then every generation has to discover what is going to be the agenda for social change. That is natural. So you have arguably the trajectory of 1950s counter-culture, 1980s slacker culture, 2010s inclusiveness culture. There is some kind of thread in breaking the mould, mainstreaming individuality, collectivising the consequences.
What is happening in the US seems a bit of a sideshow. How much is explained just by the particular kind of urban~rural divide that characterises the states? Is that such a thing anywhere else in the world?
So it seems complicated. But the left vs right lens probably tells us very little of interest.
Social discourse in general has embraced the internet. And that is going to look like something for a start - disruptive, disintermediated, ADHD. Worldwide, bigger things are going on. And in claiming both left and right are embracing identity politics/demolishing democracy, Fukuyama is mashing up the progressive and the conservative, the inclusive and the privileging, the young and the old, the urban and the rural, and all the other natural polarities that are the historical dynamics that need to be more clearly understood.
