Yes, exactly.
And their hints or outright statements that they are addicted to porn are alway so cutesy-clever, so full of smirky pathetic humor. Because people who are subject to compulsions and addictions always know that they are less than fully adult, far less.
Oh, and the people who truly believe they are going to hell for missing mass on one Sunday are not totally addicted to religion?????
Its the same psychology. You can enjoy something without being addicted to it and having it run your life.
Tragically, they also don't seem to be able to distinguish between porno and the love act established by God that is reserved solely for a husband and his wife.
As you inferred, it's difficult to have an intellectually honest discussion with 'em.
