Well Xopher I think there is a message in a very subtle way... "Stick it to the Man" for at least a part of Parson's Theocratic way of thinking, thats why his Jesus saves sticker has so much meaning.
In http://www.giantitp.com/comics/erf0101.html and http://www.giantitp.com/comics/erf0102.html where he is sticking it to Ansom who he thinks represents 'the man'... Parson also wants to stick it to Stanley but can't. The utter disappointment when Tool interrupts the thinkagram with Ansom shows he was ready to have an evilgasm (to borrow a word) over being able to complete the sticking. That is why that reaction should be taken more into the context that Parson's culpablility is completely off the chain.
