Jerry Gaskill's wife was my music theory teacher when I was in High School. They're all really great guys. They don't use profanity because they were born again Christians for a long time and the music was crossover Christian (unbeknownst to most of their fans...as it should be). Even though they have fallen out with organized religion of any kind since Doug "came out" and all the backlash they got from Christian groups, I think the foundational principles are still there. They used to come hang out at my school all the time and I got to jam with them a number of times. As big as they were back then, I guess you could compare that to jamming with Muse in your High School music theory class.
