I couldnt disagree more, firstly:
1) Religion has and does kill people. You said it right, people look for an excuse whether intentionally or not. To say one has a magical afterlife awaiting them and unambiguous incitements to kill infidelsis vastly more dangerous than a belief that only one life exists. This strips someone of their fear, incorporating delusional thoughts and ideas.
Religion itself does nothing. It takes people to make anything happen. By placing blame on something (religion in this instance) we take blame away from the individual whom has created X act. The Japanese had their kamikazes. This had nothing to do with religion; it boiled down to nationalism or putting something that they felt was greater than they in front of them. People commit acts of violence for various reasons-alcohol, country, God, meth, etc. So do we blame those killing the infidels on religion or the leaders who have brain washed them? Again, let's not take blame away from the people.
2) Again religion owes it to science not the other way around. The bacteria theory has helped enourmously, instead of beleiveing it was the devil or the like. There has been so much progress which has helped mankind physically but also inherit a greater understanding - nothing that relgion can claim. Considering thousands were excuted based on there true assumptions about the world which was in conflict with the bible is pretty sad.
Hmmmm...doctors using leeches anyone? Perhaps some electro shock therapy? Science and medicine has killed plenty of people in its journey for improvements. I don't get why we have to have a science vs religion or science only or religion only stance. Why does everything have to be in absolutes? If one is going to kill themself or is hooked on drugs or whatnot and they find God or spirituality or Jesus or Allah or etc and clean up their life, can we conclude that religion has provided no basis for positivity? Did science lead Ghandi to bring peace? Did science move Mother Teresa to help thousands and more?
And how many thousands were killed due to deplorable conditions when the Japanese and those of Asian descent were rounded up and housed in concentration camps in the US? How about the treatment of Native Americans? These had nothing to do with religion, yet a lot of lives were extinguished. Religion is not the finger to point at as some evil that snuffs out these tiny innocent lives. Place blame where blame is due-the people.
