Here are mine, all of which are of equal importance to me.

1.George W. Bush-He's no better than Hitler in my mind
2.Organized religion-In my mind, it is he worst aspect of the modern world. We as a species should be evolved enough by now to realize what a fucking pointless, time-wasting, crock of shit religion is. (I'm sure to get some comments on that one)
3.Every weapon on the planet-Strive for peace everyone, for if it were everyone's goal in life, it would be achieved.

-Remeber, you can't use one that has already been stated, everyone.
