I had this thought because I recently broke up with a catholic girl I met at university. Her beliefs weren't the main problem, what made me broke up with her was the fact that I thought of her as extremely "irrational". She was the kind of girl who believed in fate, superstions and other bullshits. She also never really questioned about her faith as she was part of a pretty religious family. I think that the fact she was so irrational never made her question her beliefs because she never asked herself this type of questions.
I know there are a lot of really smart people who are religious, but I can't fathom how you can be so irrational with such a high level of intelligence.
Tossing aside those beliefs would let them see the world for what really is and make them appreciate more what's around us.
But, again, I think that most believers are religious just because they were taught to be so, and the remain religious for inertia, and pressure from their community.
What do you think about this? Does religion suppress the intellectual potential of a person?
