How far would you go to save the life of a five-year-old that you knew was in imminent and immediate danger for his life? Would you risk your life to save him from death at the hands of a violent assailant?
What is the difference between that child, and one who is unborn? If you would respond differently, then you don't see the unborn child truly as a child. That's enough to make one guilty.
I say this only to put the urgency of the situation in the proper perspective. If you knew that 1600 born children were being slaughtered simply because their mothers wished it, you would be "up in arms," figuratively speaking. (Puh-leeze spare me the accusations of violent intent.)
Non-violently, we can do so much more. Millions of us should be camped around Washington and the abortion clinics until the killing stops. That's one thing, but the list of sacrifices we should be making is endless.
In the interest of brevity, I'll leave it there.
Now, if you would use only words to prevent a mother from murdering her born child if you knew that child was in imminent danger for his life, perhaps you can truly claim that you've done all you can, but then your humanity would have to come into question.
