I was raised as a Catholic. Technically I still am a Catholic by name (once a Catholic, always a Catholic, apparently, due to some historical-political background.)
The good thing was that my parents weren't some strict religious folks and only held me into the 'basic' standards for Catholicism for the sake of tradition. I was able to branch out a little bit while growing up and looked into other sections and beliefs, but ultimately nothing stuck since even if I wanted to believe I couldn't find a reason to. I can understand why people can still be drawn into it but you would really need to be stuck in some communal/social bubble to believe something you're told repeatedly over and over. That's hard to do and have remain in the western world nowadays.
