the best way to get citations is to find certain political groups online presence and find citations through association.

the youtube channel "philosophytube" has a lot of citation of modern progressive literature, tho i have not read all citations.

They are considered part of "breadtube" political sphere. 1/3

The series "the alt-right playbook" is also a video-series that explains the perceived tactics of right-wing groups, how they are experienced, and by inference, it explains why left-wing groups are the way they are.
These are citations:

Then, i don't know a good source, but looking into "post-irony" or similar is important for understanding the current internet generation.
TL;DR ironically genuine. 2/3

sometimes i feel books are just too limiting to understand the zeitgeist, they are often out of date or miss some intersting development.

So i would recommend 2019's videogame of the year "Disco Elysium" for it's (literary) critique of communism, capitalism, fascism and liberalism.

And, again, searching for people who unironically belief things.
Mastodon users is too limiting. 3/3
