I think you're missing the point, Hashim.

There are people who do some *seriously* bad things not DESPITE of their religion, but BECAUSE of it.

Again, I'm not trying to generalize, but in western culture if you're sister goes out and gets pregnant to her boss, you shrug your shoulders and say 'it's her life'.

There are some people who think that their RELIGION commands them to go out and murder her for bringing dishonour on the family.

One of the benefits of atheism is that it puts your own life into your own hands, and it also tends to make people think that what other people do is other people's business. So they don't go on crusades (literally) to stop people drinking alcohol, or fornicating, or whatever.
