~If you really believe that OMGZ The World Is Going To End!!!!!tm on December 21st, 2012, then WTF are you doing on da intrawebz blabbing about it? Why are you not out there having as much sex as you can? Or getting as drunk and stoned as possible? Or seeing all the places that will be gone in a few years? Or telling those you love that you actually do love them...and then going traveling and drinking and fucking?
Why are you instead hiding in your little life the same as always? Cause if that is in fact what you are doing – you would not even see this is you were engaging in the above activities – then you really Do Not Believe that OMGZ The World Is Going To End!!!!!tm on December 21st, 2012 and you just need to STFU cause you're really annoying the rest of us who are trying to focus on solutions for actual 'end of the world' issues like Peak Oil, Economic Meltdown, Global Warming, Corporate Evil and so on.
On the other hand, I suppose somebody has to buy all those fucking books about The Great Mayan Doom Fest of Twenty Twelve.
