That being said, it does seem that most third world countries may be what you would consider homophobic - but is that their religion, or their culture? Same with sexism, and with population control issues.

Bit of the ol' Pontius Pilatism here, Joe. You can't so easily separate religion from culture, not even in secular western countries. The Church connives in these things. If you think not, show me evidence of any mainstream Church organisations that actively oppose them. Standing quietly by while these things go on, when you could have a strong protest voice, does not absolve one from all guilt.

And Steve, the primacy of conscience has always been taught in the Catholic Church - even conservative EWTN will tell you that. The fact that you didn't learn it, means maybe you didn't read enough, or didn't pay attention...

Well it was never clearly articulated so that we could be sure where we could or could not apply our consciences (and, er, we were impressionable teenagers, of course). Oh yes, I remember lessons in which the many kinds of conscience were analysed, and it was made perfectly clear to us that the correct kind of conscience that would permit our breaching of the Church's laws was too high a barrier for almost everyone. The conscience getout was very much on paper only.

As for not reading enough or not paying attention, I did rather well at school as it happens, thanks. Largely by reading and paying attention. Stop guessing.   

or were blinded by preconceived notions that would not allow you to understand.

Shame you have to spoil the discussion by resorting to the lame old, patronising "bitter ex-Catholic" ploy, Joe. I really can't be bothered to keep on refuting it.
