Does Anyone Know of Political Activist Leaders that Speak Like Later Years of MLK Jr. about Evils of Capitalism, Freedom & Etc., No Matter which Party It Comes from, But Without Religion of Any Kind?

This morning I watched ‘Free Speech’s ‘Democracy Now’s The MLK Jr. episode (every MLK Jr. holiday, they have a MLK Jr. special episode) with his speeches, it was awesome, but at the end I was thinking to myself are there any Atheist Political Activist Leaders that Speak Like Later Years of MLK Jr. about Evils of Capitalism, Freedom & Etc., no matter which party it comes from. I have yet to found at least one, in all political Left-political Far Left media I experience, over 2-decades. Then I was like I will just have ask you all here.I know that MLK Jr. has been one of THE GOATs, if not THE GOAT, when it comes to public speaking. The only Political Activist Leader person I can think of that talks about Evils of Capitalism (leads ‘The Poor Peoples’ Campaign’), Freedom & Etc., no matter which party it comes from & comes close to being as good as MLK Jr. is Rev. Dr. William J. Barber II.. The problem with Rev. Dr. William J. Barber II is he obviously inserts a lot of religion into his activism.
