You really think so? Stereotypical stuff he did that you would expect from ultra religious people:
*Scoutmaster for Junior Campers:
*Obsessed with church and Bible (he actually wanted to ask Reverend Lovejoy if it was OK to play Capture the Flag on Sunday) and goes to church every day
*Part of the Citizens' Committee on Moral Hygiene (the conservative groups who think they have a right to tell everyone else what they can say, watch, and do)
*Doesn't gamble, smoke, curse, or anything similar.
And so on. Don't get me wrong, I thought he was a great character even early on, but he was a parody of religious stereotypes very early on. Once they had him have that mid-life crisis though, it gave them room to grow by finally letting him become angry at people and say when he is upset.
