Skeptics are often asked: What’s the Harm? What harm does it do to believe in weird things especially when it comes to religion. The answer is that plenty of harm can come from the innocent belief of lies. There is now a web site where you can track the harm done. The web site is called What’s The Harm and lists the harm cause by “innocent” belief in topics as broad as Medicine, Religion, Supernatural and Pseudo-Science.
As of this writing the harm has amounted to 3,247 people killed, 224,674 injured and over $277,416,000 in economic damages!
I highly recommend checking out the site.
