Don't you guys think that religion makes the world more interesting? It defines cultures, differentiates them.
Personally I find that video shocking, but interesting. And that's what makes it worth while, it's something different. If we were all the same this place would be boring.
It has caused lots of problems, millions of people have died or had their lives ruined because of religion. But I'm pretty sure that religion is just an excuse and if it didn't exist, people would easily find a reason to fight each other over something else. Football hooligans for example? It's on a small scale, but the principle is the same.
edit: Another thing I don't understand is that you shouldn't talk about religion. What's the big deal, if you tell a Christian that you don't believe in god straight to their face, will they go off and cry or feel bad because of that? We believe in many things, maybe that a political party is doing a good job or not. But politics isn't considered a touchy subject now is it. If somebody disagrees with us in such areas, we discuss it, try to understand the opposing view and convince the other person to ours. But with religion it's always better to keep quiet? Or do Christians feel like you've just told them that their wife/husband is fat and ugly?
