Interesting discussion that has nothing to do with the topic this has turned into.
As far as religion goes, Tyrant is bob on, we've had thousands of years for there to be any evidence of one of the many hundreds of gods there have supposedly been, yet still not a spec. Saying there is no god(s) isn;t arrogant, it's a factually based statement and absolute common sense.
On art though, blah blah, meanings, etc. Awa min, art should be decorative additions to a home or in a gallery where you can go and gawp. Where it started going wrong was when it moved from that to modern art that had "meaning", and then just any old shite dressed up as "art". Tracy Emin and her like are just the Dom Jolly of the art world, absolutely taking the piss. "Hey, here's a dead cow in a jar, what's that about"? It's about taking the fucking piss that's what.
