Naiomi, nobody (these days !) forces anyone to follow any particular faith. And don't go the children route ... they grow up and make their own choices in their own time as mine have done and as I did in my time.
Which means there is nothing to stop anyone who does not agree with the church's teachings from leaving and finding a faith (there are plenty out there) which is better suited to them .. or from dropping faith altogether.
Basically if you don't like the rules of the club, you have two choices, leave or work to get the rules changed. So far the rules have been moderated slightly by the current Pope's thoughts on the matter of condoms, but his thoughts are not official teaching as far as I know, though they will be treated as such.
But to keep banging on about how the church's teaching contribute to the spread of AIDS is daft when, if followed, they patently do not do so.
