I'll tell you this the same way i might not tell a little child not to stick a fork in an electrical socket. I'm happy to know that there is religious people who are, at the same time moraled, not stuck up the churches ass. But I fail to see the moral question in filming a hubby and his partner getting it on for the sake of redtube over religious propaganda.
If you get money for filming porn, it's not like you have done anything wrong. I have never heard the argument that the producer is personally in the wrong but rather the thing as a whole. However, smut is smut no matter what it comes out of, If i had to choose between propaganda and porn I'd go with both.
No matter what you say, the difference between a doctor and a lawyer is career only and trying to pretend that your smut is less smutty then the smut made by actual smut is pretentious. I understand your dilemma but when you think about it, your porn flick will reach tops 1,000 people on redtube but no one will seriously remember it, meanwhile your propaganda will reach 1,000 people minimal and will convey this message to the new age: join or die. So, your choices, Join or Die, or a 15 min porno.
(please note, I do not care if your porno is 3 hours long, no one seriously watches a whole porno movie so it might as well be several 15 minute pornos)
