I actually find C. Derrick Varn's podcast really interesting and informative. I was going to recommend a specific podcast, but his public and patreon feeds have a very loose correlation with episodes coming out months apart on the two feeds. He claims he will finally cut back on his output, but so far he releases almost 5 episodes a week and is one of the most prolific podcasters despite having a day job.

I am mostly promoting this because of how informative I find this podcast, but also because Varn is having some health issues and a crisis of faith in "the left". So, if you are interested in theory, check it out.
