Generally, I would agree that Protestants are better, but this is not always true. Let me use myself as an example. A lot that has been said by others here will be supported.
I am a ‘cradle Catholic’. I went to a Catholic school until the 5th grade. During this time it was just my father and I at home. The only time I went to Church was during school, when the kids were upset at having to go. Needless to say, by the time I switched to public school in the 6th grade I was not very spiritual. Though I took had taken religion for 6 years, I knew little of my faith.
Through my three years of middle school religion was not a big deal to me at all. My grandmother made me go to a Catholic bible study group for kids my age. It just upset me more to be forced to go. I found a group of kids I could cause trouble with. In the 8th grade, when I graduated from the class, I went through Confession. I was not anywhere near a strong Catholic. In fact, I started to question why I was a Catholic anymore. I didn’t feel Atheist. I was just about ready to convert to the religion of quite a few of my friends. They go to a UCC (United Church of Christ) church.
I attended a few times, and it seemed goofy to me. The preacher would preach to the group for an hour about a single verse in the Bible. They had these all so great rock tone…real modern right…the problem is that I’m a rock fan and they all sounded like echoes to me. Furthermore a trip to my Baptist grandparent’s house repulsed me from Protestant religions even further. So I started going to the Catholic Church up the street myself. I started asking the Priest questions. I love knowledge. I’ve read works by Plato and Machiavelli. Socrates’ debates thrilled me greatly. So now I was armed with my Catholic ‘faith’ and knowledge. I was ready to debate.
I started debating anyone of any Christian religion. I was dead set to find the truth. I got a Catholic bible and a Protestant one. To sum it up, I now attend Church every weekend, unless I am out of town. I’m open to all religions, but sound in the Catholic religion. I’m still a high schooler and I’ve switched from reading philosophy and physics to theology. I can debate an Atheist or non-Catholic just as well as a convert of MY age can.
So yes, I just think it depends on your mindset. Your mindset often depends on your experiences in life.
