Brought up as a Catholic, went to Catholic School, felt no connection. My father is pretty irate at this. He and his parents were persecuted and eventually kicked out of Ireland just for being Catholics (it's not like that anymore - I hope not anyway), but I only say to him that's precisely why he should be ditching that stupid voodoo magic Jesus Christ mumbo jumbo. He just doesn't get it. I'm aware it runs much deeper than that, but honestly it's really not worth it anymore. Why insist on following a useless faith that eventually got you chucked out, never allowed to return for another 56 years? I treat the whole Catholic/Protestant situation with utter contempt, and it's probably where my general anti-religious stance stems from. I know the Islamic Shia/Shiite/Sunni factions have it far far worse.
I DO believe in something, but I just think the existing religions are utterly retarded as ways of portraying a belief in a higher existence. Less infighting and bickering, and more appreciation for the mysterious thing that sparked the existence of everything as we know it in the first place please. (oh, and less of the fancy dresses and downright ridiculous rules and laws)
