"But if people disobey the Pope and have sex outside of marriage, why should they obey the Pope about the use of condoms? There is no logical connection, none at all"

Joe, Yes, you have your local belief that all, or at least most, RC people you know (I suspect USA folks) disobey the Pope, or that he has no or minimal influence on their lives (that you have more).

That being well stated, where is the research proof behind your broad conclusion, that you seem to claim to be logic or common knowledge, that people in third world countries, for example RCs in Africa, are not influenced by statements by the head of the RC church, let's say on condom use Provide such research citations please.
