I'm not sure if it's real, but it's funny. I've been to several private LAN parties and they can be fun, but a lot of them have a lot of cussing and vulgarities (if you think gaming with voice chat has lots of cussing, just imagine a LAN party without any language rules). I know if I was hosting a public LAN party that required an entrance fee, I'd make all who enter sign an agreement prior to entering that if they're caught cheating their rig will be destroyed or confiscated. I'd have an attorney write something up for me to make sure everything was Kosher.
As a side note, I can certainly agree that a LAN party at a church, especially for a first person shooter, is quite strange and I daresay inappropriate.
Research shows that one in three Clinton supporters are just as stupid as the other two.
