YOUR tax dollars are going to be used to force women to kill their unborn babies.
1) supporting 0bama constitutes material cooperation with intrinsic evil
2) you have a moral obligation to reduce (legally) the amount of tax dollars they have available to use for this purpose
Also, membership in the United Nations constitutes material cooperation with intrinsic evil. If America were to withdraw from the UN,the UN would be in a world of hurt without us helping to prop it up.
