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.
