Too often I listen to and read apologists that use the phrase "But what's the harm? These are private beliefs, and who are we challenge what people believe?" Well, all too often, irrational beliefs that are acted on cause a great deal of harm. Just look at the fantastic website What's The Harm. "3,284 people killed, 306,068 injured and over $2,815,114,000 in economic damages ..." and that's just the beginning.
The three terrorists known as the Bali bombers are due to be executed by firing squad sometime within the next day or so. In 2002, they targeted nightclubs packed with western tourists, killing 202 people, 88 of which were Australians. They have never expressed one ounce of remorse, with Amrozi often seen with a huge grin on his face, which gained him the name "the smiling assassin."
They view themselves as martyrs for their religion. Their brother believes that when they are executed, they will be placed in paradise because they stood up for their religion. Their mother is pleased that they will be put to death, again because they will be martyrs for their religion and will be sent to paradise. There are no doubt countless others that believe the same thing.
In the interview below with CNN, the interviewer tries to insist that the bomber is "twisting the Muslim religion completely", however the bomber is able to point out an exact passage in his holy book that justifies killing for his religion.
The interviewer asks "What gives you the right to take the lives of other people?"
The bomber answers "The verse... blood by blood, soul by soul."
That is the harm.
This also raises another point which I often struggle with understanding. These people not only believe that they are right, they "KNOW" that they are right and are willing to give up the one life that they are certain to have. If you don't hold the belief that they do, then you are either going to hell, or not going to heaven, or whatever particular teaching that religion has. Then there are people from other religions that make similar claims about their own belief systems, and they believe and "know" JUST as much as the other group. It goes on and on, with countless religions making these claims. Some one MUST be wrong. They cannot all be right. Yet each group is just as convinced as the other, and in some cases willing to die for the cause.
As an atheist, I reject all claims of any type of god/s until I have good reason and am justified to believe. Hence there is no dogma, no beliefs to follow, nothing to worship, nothing to want to die or kill for, and in fact makes me love and enjoy every day I have in this life, doing as much good as I possibly can.
It seems to me that atheism makes far more sense.
