Well, Mary Sanchez got one thing right in her column: (7/21: “Randall Terry won’t go quietly, if he goes at all”): I hate getting old! (But it sure beats the alternative.)

And she is right: In my fight to end abortion, I am stuck in the ’80s – and the ’70s and the ’60s: The 1880s, the 1770s, and the 1960s, that is.

Every social revolution in American history — whether civil rights in the 1960s, woman’s voting rights in the 1880s, the abolitionists in the 1850s, or the anti-child labor movement of the 1900s — used incendiary rhetoric, offensive images and clamorous activism.

What do you picture when you think of the civil rights movement? Lunch counter sit-ins; illegal marches; women getting arrested; black men being hung by the Ku Klux Klan; police with billy clubs; dogs biting protesters, water cannons and a lot of bad press.

The abolitionists and the suffragettes likewise offended the sensibilities of polite society. The abolitionist William Lloyd Garrison said: “I do not wish to think, or speak, or write, with moderation … I will not retreat a single inch—and I will be heard.”

Ms. Sanchez also observed, “The anti-abortion movement changed tactics.” She is right, and she accidently explained why the pro-life movement has been steadily shrinking as a political, cultural and media force the last 15 years.

Unless we reverse course, and create and expose social tension in a fierce and deliberate way, the pro-life movement in America will become politically neutered, and child-killing will be with us for 100 years.

Sure, “women in black, coffins filled with ‘blood’-covered fetal dolls … an audio tape of a newborn crying” are agitating and offensive. But the reality it represents is far worse.

All of the social revolutions I referenced used similar tactics to help reach legislative victory. No one can own a slave; women can vote; young boys are not dying in coal mines; and black Americans can ride in the front of the bus all the way to the White House.

Our mission in this battle is to make it illegal from conception until birth to kill an unborn human being. For total victory — as in social revolutions past — we must employ the words, deeds and images that propel political change.

If I get “a second act,” I do promise a “few new tricks.” And I promise that they will come from the playbooks of social movements in our past.

Believe me, if I could figure out a way to burn a bra and have it draw attention to the injustice of slaughtering the unborn, I would do it.
