Just my opinion..but I feel like this song is throwing up two middle fingers to organized religion.
With all of the preaching and then he shouts "Can I get an amen?" Baaaa! "Can I get a hallelujah?" Baaa!
To me it seems as if followers of organized religion are represented here by the sheep. They all follow and conform to religion.
As for the rest of the song...I'll just look at the other threats an piece together my own interpretation based on what you guys think.
