I think to a large degree this song is about the harmful psychological effects of literalist/strict ("fundamentalist") religion. Specifically, the way it saddles people with guilt for being human (being imperfect and having deisres and drives), especially with regards to sex (IE the lines about dirty sheets, etc.), which results in people beating themselves up over things they often know (but have yet to convince their subconscious) that they shouldn't even feel bad about (crucifying). Furthermore, it inspires a spiteful, judgemental, "holier than thou" attitude (the lines about pointed fingers and a kick for a dog begging for love) which tends to destroy interpersonal bonds, especially between parent and child, and hence often results in children from these families looking for love (or a cheap, easy substitute) elsewhere...like in irresponsible sex (looking for love between dirty sheets again), though they may feel very guilty...
