Hands down Religion is the most destructive force know to mankind. Combined with racism and you have one tough bitch to handle. And if we are not careful religion will be the death of man. Every major war has a reason - expansion, wealth, power, greed but religion tops it all. Religion can destroy a nation and it's people and if you though that religion is the reason for our morality - we have morals inspite of religion! The idea of a god was first created by thinking men as a means to explain that which we cannot explain but it has since evolved into something much more complex and dangerous.
Despite all the progress we have made as a species, we are still held back by the disease called religions. Imagine what all we could have achieved if it wasn't for religions. We would certainly be exploring the galaxy by now! Religion is like a cancer; it spreads and fucks up everything in it's past. As I type this some hindu fundamentalist leader is planning the next attack against what he thinks is "immoral", some muslims are planting a bomb and christians fundamentalists are plotting to terrorism a non-christian community.
Religion keeps us from progressing. My family's religion wants all of us to forgo everything and stay at temples, singing prayers and kissing the ass of some deity. Do nothing except that while our families are taken advantage of by fake "swamis" and give up our worldly possessions. Your religion does too. Most religious people don't realize what the Bible, Gita, Ramayana, Quran, Torah really are - bad science fiction & fantasy novels! I like Star Trek - that doesn't mean that I'm gonna be beam up anytime soon! Or apprehend someone because they violated the Prime Directive (lol, I am killing myself). Grow a brain!
