The ESRB is not a Christian organizations. It does not rate things based on "biblical law." This link has nothing to do with ESRB's rating system.
A tidbit of information for you, this is who the ESRB is: Activision, Atari, Capcom, Crave Entertainment, Disney Interactive Studios, Eidos Interactive, Electronic Arts, Her Interactive, id Software, Konami, LucasArts, Microsoft, Midway Games, Namco Bandai, Nintendo, NovaLogic, SEGA, Sony Computer Entertainment, Square Enix, Take Two Interactive, THQ, Ubisoft, Vivendi Universal Games, Warner Bros. Interactive, and Wild Tangent.
They are most certainly not Al Menconi.
