If you are religious, you believe that your religion is the 'right' one—and, in many cases, all others will be sent to hell. Similarly, a nationalist believes his or her nation is better or more advanced—and a racist believes that an inherent difference between each race make his or her ethnicity superior. All of these ideologies spawn the hate, philosophical disagreements, and prejudices that have been the catalysts for various atrocious acts throughout history.

Religious people claim that it's just the fundamentalists of each religion that cause problems. But there's got to be something wrong with the religion itself if those who strictly adhere to its most fundamental principles are violent bigots and sexists.

Miracles are commonplace in religious scripture. Our ancient ancestors are said to have felt Jesus' wounds, verified Muhammad's ascent to heaven, and even interacted with their respective deities directly. Today, believers have no such luxury. They are forced to rely on blind faith that these things occurred, that people were at one time able to overcome or render inert natural laws.

If there's a god, it knows exactly what it would take to convince me and has refused to provide it. In fact, it has gone to great lengths to hide any evidence of its existence. That doesn't seem like a deity that wants to be worshiped to me.

Prayer doesn’t work. Perhaps it makes the believer feel better (in the same way that meditation or deep thought would), but prayer doesn’t actually affect the external world. Not only is it ineffective, but it is also a very narcissistic practice… why would a 'God' change its 'Divine Plan' to accommodate any person’s wishes?

Not only do I believe that it is possible to maintain moral standards without the crutch of religion but I would argue that it is the only way to achieve true goodness.
