Read the book Londonistan , and then read the book series that begins with Prayers of an Assassin . The world is succumbing to now-radicalized Muslims. You know what place should remain safe? Iceland. That's why I am going to move there. I should start a forum club called the "Virates", which are Viking Pirates, and kick ass. EDIT: You know what else kicks ass? Viking metal. Amon Amarth is NOT true Viking metal, just death metal about Vikings. True Viking Metal is Thyrfing (before Vannisevior (I didnt spell that right) ) , Bathory (after the black metal era, before the retro-thrash era), Falkenbach ( one man band FTW!) and many others I have yet to discover.
http://metal-archives.com is a good place to find metal.

Viking metal is quite diverse. It can be almost thrash-like, if done right, black metal, folk metal, or a hybrid of these.
