"What’s your pro-life elevator pitch? Let us know!"

"I feel that all humans should have a chance to live free from violence."

(I borrowed most of that sentence from somewhere.)

PCers tend to blink, and then not to immediately become pro-life, but at least to respond by going straight to what they think justifies abortion. That clears the air for a discussion, or if there is no time for a discussion, perhaps at least leaves them still thinking.
