It kid of irks me when stuff like this comes out. P&P RPG's get so little attention as it is, and 90% of the time when it does, gamers are painted as socially inept girl crazy man children. It gets even worse when they misrepresent the game itself by making up their own rules set which enforces these horrible stereotypes (+4 shyness?)
The average D&D player isn't far off from your average video game player, which is to say we come in many shapes and sizes. Even for comedic effect there are many humorous stereotypes of gamers that don't end up being repulsive to humanity the second they leave the table. I'm tired of having to defend myself to anyone who sees my gaming books and only has drivel like this and Stephen Lynch's "it's D&D" to base their opinion of my hobby on.
Are there players like this? Yes but from where I stand it's far from the majority. Things like Dorkness Rising and Something Positive have done a much better job of portraying gamers while still being hilarious without being like this. Honestly this may as well be to the gaming community what blackface is to African-American culture.
