I'm Catholic (although I think religion is mostly nonsense), and I am missing part of my anatomy. For whatever reason Americans don't like foreskin, it's not just a religious thing.
I kind of like the concept of Lent--that you can make a change for 6 weeks that should conceivably be for the better. If everyone gave up meat one day a week everyone would be healthier and we could reduce greenhouse emissions (sorry mjrod.)
