I think Jon needs to take a break for a while and regain his inspiration. Burnt Offerings, Dark Saga, Something Wicked, and Horror Show are some of my favorite albums of all time, but I feel like Schaffer has lost that edge over the past few years, and Sons of Liberty is no exception.
Additionally, I've always hated political music. Music has always been a way for me to escape from shit like politics, so I've never enjoyed politically driven albums. I'm a conservative, and the political shit in this album still way too prevalent for me to be able to enjoy the music. (not saying I agree with everything Schaffer believes, but I'm not on the other side of the spectrum as some people are)
