@bike You might consider the source of who wrote those history books, as tearing it all down is also how progress has been won. I think everyone has a different path if you're interested in a more radical understanding, but if you're starting with history and you're bringing up the US, I would maybe start with Howard Zinn's *A People's History of the United States*
I'd also direct you to just read more radical works by radical authors. Read the books and authors that fascists hate. Read citations. I am an anarchist, so I'd probably want to point you anarchist thinkers, but I'm not sure it's always necessary to start there. Maybe start with James Baldwin or Abbie Hoffman, then maybe Noam Chomsky or David Graeber, then maybe Proudhon or Kropotkin or Emma Goldman, but learn the history from their eyes, not the eyes of those in power, not the conquerors and the oppressors...
... you might even start with Ursula K. Le Guin's *The Dispossessed*
