I have widely varying assessments of the praiseworthiness of different religions (and I also note that some of the more praiseworthy ones are also some of the more patently untrue, in terms of specific beliefs). However, I have only one assessment of political systems that allow members of one religion to forcibly impose their beliefs on others -- they suck, and lead to a lot of violence and misery, as well as stamping out individuals' honest search for greater truths.
It's never a good idea to be TOO sure of your religious beliefs. Those terrorists who took down the WTC were just as sure that their religion is the absolute ultimate truth, as you are sure that yours is. Oddly, your Pope is a lot more flexible than you are, about seeing truth and value in religions other than the Roman Catholic Church. Maybe you should spend some time seriously contemplating his teachings on the subject.
What truth has the Pope seen in non-Catholic religions?
If you read that encyclical I passed your way and realize that the Church has always taught the same system of faith and morals, I will do just that.
