I can only say good for them. This post from the Courage to resist blog:
Wrong is easy. Right is difficult and long. Do what your heart says is right.
We knowingly and willingly make this plea to you in violation of 18 USC Sec. 1381 and 2387 (see below). We knowingly and willingly embrace some of your risk by urging you to refuse duty in the U.S. military.
We plead with you, as Bishop Oscar Romero pleaded with Salvadoran troops: "When you hear the words of a man telling you to kill, remember instead the words of God: 'Thou shalt not kill!' No soldier is obliged to obey an order contrary to the law of God?In the name of God, in the name of our tormented people who have suffered so much and whose laments cry out to heaven, I beseech you, I beg you, I order you in the name of God, stop the repression!'"
If you choose to leave the military, please know that our hearts and homes are open to you.
Now those are indeed powerful words. I'm not a Christian, as i've stated before, but when Christians speak out against the evils of war, I will stand in solidarity with them.
