"The primary points of contention between the atheist and the religious person are how the universe was created and what happens after you die."
No, totally not.
Do you know who conceived of the 'Big Bang'?
It was Father David LeMaitre - a Catholic Priest - and Physicist.
The Catholic Church is 100% behind the 'big bang' and 'evolution'. There's little dissonance between the church and science.
The 'difference' between atheists and religious types - should be better described as the difference between 'materialists' and 'spiritualists'.
'Materialists' (atheists are usually de-facto this) - believe that the material world is all there is, and that's that.
'Spiritualists' believe that life is an expression of something greater.
'Science' is actually rooted in Metaphysics, which is the trunk of the tree below 'Physics' (see Descartes). The problem with most scientists/rationalist/atheists today is that they have forgotten their metaphysical underpinnings ...
"Both have very little effect on actual day to day living."
I see what you're saying - but maybe not.
If you believe in something greater than you, you might be more inclined to think much more long term, make sacrifices for the greater good, for the community, for future generations.
If one believes that 'this is all there is', then one might be inclined to simply pursue highly selfish and hedonists endeavours, because after all 'sympathy' and 'empathy' are just 'emotions' - and in a purely material world there is no 'right and wrong' etc.
It'd be nice if all schools at least taught metaphysics in high school, i.e. the underpinning of how we think about the universe. As it stands, most public schools teach a very materialist viewpoint by default.
And yes, there are tons of atheists in 'Catholic Schools' because they tend to be very good. You should wonder why all those crazy religious catholics basically invented common education as we understand it, and established most of the best universities (100% of the Ivy League, Cambridge, Oxford etc. etc. :) :) (mostly not Catholic, but religious nonetheless)
Anyhow - it'd be nice for people to have a little more choice in education, without having to entirely deconstruct public education, which is important.
P.S. I'm not Catholic :)
