As a devout Christian who enjoys games like Diablo and Doom, I wanted to offer a different perspective. All of my Christian developer friends (small pool but still large, at around 15 people), including myself, have no issues with tech terms like daemons, master/slave, or killing processes (esp. child processes). Many of us understand the context and humor in technical jargon. In my experience, it's often non-technical people rather than Christians who find these references odd. But then again, what non-technical people run nmap?

Just my .02c :^)
