Not everything is perfect at all - there are very serious problems - but the country (and world) is transformed since before the Civil Rights Movement, and civil rights have spread to others (LGBTQ+ and disabled people, for example).
It's the people against civil rights who want you to quit, to believe you are powerless, that it is all for nothing. Maybe they want to believe it too! :)
That only started in the last two decades and in many places it's still a far cry away from being properly established.
Plenty happened in the four decades before that. Look up Stonewall, for example.

That doesn't mean nothing happened. People can get married, and most of the country supports that!
Your complaint is that it's not a documentary?
Some people certainly would like to silence any discussion of it, and they have every argument in the book. Disdain / contempt are a popular tactic.
I think the thing about For All Mankind that makes me sad is how it conveys the potential that the 60s really offered but failed to deliver on, in terms of progressivism, equal rights, womens roles in the workplace. Of course it’s a work of fiction, but science fiction has always been a mechanism for exploring different socio-political evolutions and it makes me feel like we missed something important that we’re only just on the cusp of today.
Anyway, my 2c
