Religion has done a few of these things: * Condone slavery * Condone gender inequality (Islam and Hinduism is big on this one) * Condone intolerance of others belief, which led to killings * Go against logic, reasoning and practicality, which has proven to work. * Promote untested theories (Creation, prayers) and beliefs (faith, etc.) From all the crap I've seen between between the Muslims, Christians, and Jews in North America, Europe, Middle East, Africa and the Philippines. The Hindus and Muslims in South and East Asia. The Muslims and the Buddhist in China. And the Hindus and Buddhist in Sri Lanka. I think it's safe to say that religion cause more problems than helps. Yes, religion does a good job of bringing people to a common cause, but is that common cause a beneficial thing? For most of the time, yes, but you can do it without religion. All in all, we would be better off without it. With reasoning, logic, and common sense, we can achieve all the things that religion can with less drama.
