I know Greg Graffin's the Bad Religion member who does the whole public philosopher bit, but I lowkey suspect that Brett Gurewitz has the more philosophically interesting positions, at least based on a close read of their respective lyrical contributions + interview comments relating to them.
To be clear I'm an absolute sucker for all of BR's whole bit, but, I think I find whatever's going on in here to be a bit more interesting than the "atheist wrestles with the symbolism and void spaces traced around the image of a god they were societally inculcated to expect, but which is clearly absent" thing that Graffin tends to dwell upon.
