You make an important point here. I think one difference between the "divisiveness" of today and the more (I think) serious and literate divisions of the sixties may be the intervening half century of cultural infantilization. One of the consequences of that is a sort of triumph of superficiality, relying on various cut-and-paste ideas and stereotypes that don't allow much granularity between individuals and situations. We seem to have limited our social and political vocabulary to a few simple symbols, acronyms and plotlines. Even zip codes.
This leads to comical confusion. You can refer to yourself as "antifa" while putting on a black shirt and attacking people whose ideas you dislike with apparently no idea of the historical association with the Blackshirts of the past. Any violent incident is automatically forced to fit a pre-existing narrative framework. We have simplified our thinking to the point where even the existence of certain ideas or attitudes make some of us feel "unsafe". Get a formulaic phrase wrong, and you are beyond the pale.
At the apex of the great pyramid of cartoon thinking is the white "cis" male. The source of all villainy and the architect of all oppression. Many are unequipped to think beyond that. Even white skittles must answer for their crimes.

In my view, the most effective opponent of the Trump Administration is a white man. His name is James Madison.
