The article starts with a simple question: “If someone wants to believe in something completely ridiculous such as religion, why should atheists care?”
The answer is simple:
As a point of fact, religions are dangerous. People use religion to justify the most absurdly cruel acts and attitudes. Few will argue that religion was the principle motivator for the 911 attacks.
And 9/11 is just the tip of the iceberg.
If people just believed ridiculous mythologies and didn’t act on those beliefs, atheists wouldn’t have a problem and probably wouldn’t spend any amount of time refuting the ridiculous ideas of religion. If I run into a crazy person telling me that Elvis is still alive or that Martians inserted an anal probe in his or her butt, I don’t sit down with the person and go over the logical problems with his or her beliefs. But then again, these people aren’t out there making laws based on their beliefs either. Nor is there a significant voter block trying to push politicians for more Elvis based laws. These Elvis believers aren’t stealing tax payer money in the form of tax-exempt statuses or trying to define marriage as having to be preformed by Elvis impersonators.
Religion produces vile behavior. Then the religious want their behaviors turned into laws that affect everyone.
