The “Survivalist” series had so much filthy language that I returned it (to Audible) after 1 hour of listening. I’m not sure if there’s a profanity filter for Audible, but that was an issue for me as a Christian man. Just not worth it. For that reason I liked Rawles’ “Patriots”. I just bought a Kindle version of “A Failure of Civility” which looks very good.
