Nelliemoser - I am interested in all religions or other philosophies, but it seems to me that the undemocratic nature of the Catholic church, and the influence it has throughout the world, makes it the one that worries me most. The Anglican church is a bit wishy-washy on most moral issues so it is not as challenging as Catholicism, which claims to know all the answers. I have very unpleasant memories of the treatment meted out by some nuns when I was at school (not to me, I was a teacher's pet) and the snobbery and unfair advantages given to girls whose parents were well in at the church.
I am particularly incensed by the world-wide misery caused by the church's stance on contraception, abortion, divorce and homosexuality. Some other religions are equally culpable but are not, in general, as powerful in Europe.
The only quarrel I have with individual members of any church, is that I find it hard to get them to engage in debate about what they actually believe - they seem to become very defensive and reluctant to enunciate their beliefs.
If I were a believer, I think I would be very happy to tell everyone exactly what I believed.
