I've been at this (pro-life ministry) for 20 years. I've always shied away from telling someone in (any) ministry that "you're doing it wrong".
Just sayin'
I’m going by what Abby Johnson et al have said and what I know I would have done.
Being screamed at does not work. I mean if you at Wal Mart and some crazy person screamed at you what would you do? You’d run away from that person maybe call the manager or police. So why do you think it’s any different at an abortion clinic?
Yes I know feeling run high because of what is happening at the abortion clinic but that is no reason to lose your head over it. Keep calm. Those people got Abby Johnson out and they never screamed at her.
And on each of those 3 or 4 times, the organizer of the prayer vigil approached the "yellers" and gently but firmly told them they must either stop yelling, or leave the sidewalk.
The international group 40 Days for Life --- absolutely worth a click --- like many other lifesaving groups, requires their participants to sign a Statement of Peace, pledging not to confront, yell, name-call, make physical contact, or in any way incite or participate in anything that could provoke violence.
This reflects what many other FReepers have said, that the idea is to get the woman to approach you, not to run away from you.
This actually is effective. 40 Days, since 2007, has helped over 16,000 women turn away from an impending abortion --- and those are the known cases, who knows how many more?
Abortion is indeed murder, but it is in some ways unlike any other kind of murder. The principal difference is this: the potential victim is utterly physically helpless and INSIDE of the potential perpetrator. There is no way to rescue, reach, or help the baby in any way, unless you first gain the mom's permission and trust.
You can only embrace the baby by loving the woman whose body already embraces him.
(You already know this, but I write also for the lurkers.)
