Maybe if more Americans knew how much we were spending on war they would be less inclined to support it. "Death and Taxes" is a well-known and clear infographic of government spending:

It shows military and security spending as 63% of the 2011 budget(895 billion).
The discussion here seems mostly about the income tax, so I'm focusing on that. I'm not morally opposed to paying taxes to live in a civilized society. I AM opposed to two thirds of my money being spent on instruments of death and building up the American war machine.
63% of the discretionary budget.
If you look at non-discretionary spending as well, you'll see that it's like.. less than 20% of the money spent.
And remember, we don't just pay federal income taxes. We also pay state incomes tax (most states), sales tax (most states and locales), property tax, item taxes (like luxury taxes), FICA tax, etc...
While I'm sure a LOT of money goes to the military, I'm not sure I believe it is most of it.
