What year do you say the 60s ended musically? In 1970...

>If we go by eras in general, and not just musical eras,
I'm going by overall eras, not just eras within specific parts of pop culture. The shift started with the early MCU. I'm talking about the shift they had on pop culture, not the shift within the properties.

Personally I haven't noticed an actual change in progressive politics from identity politics (which are still a huge part of them) to the socialist side outside of reddit.

>The shift started with the early MCU
From what I remember they were just average movies until Avengers if not later. I mean, Iron Man is clearly part of the previous tradition of superhero movies.

I have. But that's only half of the story. The rise of the alt-right on the same year and the ongoing polarization are important to note too.
