That's really the only question to consider. As horrific as they are for us to look at, do they work? Is there an objective way to determine how effective they may be?
The goal here is obvious. If it advances us towards the goal, use them. If not, do not use them.
If holding up celery sticks did the job.... what I'm getting at here is the decision on whether this is a valid tactic needs to be, solely, to they discourage women from having an abortion who otherwise would more so than another image, say, of a live child via a sonogram.
Very hard to focus group, as you might imagine.
One of the most powerful weapons for evil is darkness, evil seeks a darkened place. The message that abortion is not wrong has so permeated our world that the stark truth of the salughter is perhaps the ONLY thing that can penetrate the darkness now. Sadly, too many will be repulse, but because they want to join to the darkness to hide their deeds under the blood of their alive womb-bound child sacrificed, they will attack the bringers of the reality rather than see the evil for what it is. It has been said that televising a partial birth abortion killing for all the world to see would stop that evil dead in its tracks. I kind of agree with that, yet I am repulse by the sick thought of slaughtering a live child on TV to get through to this sick world.
