>"Currently, the U.S. Postal Service receives 99 percent of its operational budget from the sale of postal products (stamps) and postal services. The remaining 1 percent comes from the U.S. Government. This 1 percent is compensation for “free franked mail” for members of Congress; “free mail” for members of the military; and reduced rates for non-profit mailers — i.e. churches, charities, etc."
So I was financing organized religion despite my convictions... Come to think of it, I was also financing some wars and measures against liberty.
I hope I did something good on some other side, to balance this.
