i THINK it plays out like this
dad: "son, i saw you lookin' at titties and gash on teh intarnets."
son: "oh no!"
dad: "yeah, that means yer a filthy queer."
son: "but i was looking at naked girls!"
dad: "well, son, see, looking at porn means that you aren't with a real woman, but are actually with yourself, and you're a dude, so that makes you a gay."
son: "i am confused"
dad: "sexually confused, that's right! praise jesus and tom coburn for bringing you to the truth! now remember that if you ever lay a hand on your dick with onanistic intent you are a homersekshul and also god will hate you and you will die of the aids."
son: "did you ever look at porn, dad?"
dad: "never. now i am going down to the local truckstop restroom for nasty al's, ah, prayer service. tell your mom i went bowling. good bye!"
thus do republican fathers pass their values onto the next generation
