How about a 'matter-of-fact' photograph of a medical waste bag full of dismembered unborn children taken from an abortion facility dumpster? Some of these abortion photos were actual taken by the abortionists themselves to reduce their medical malpractice liability. Apparently the body of the child sometimes needs to be reassembled after it's removal to make sure all of the "pieces" have been removed from the womb. It doesn't get any more 'matter-of-fact' than that.
That is the case in all D & C abortions. The baby's body is usually reassembled on a table to make sure that no body parts are left inside which could lead to infection.
And apparently these people sleep at night.
I guess for me one of the scary things the Holocaust Museum showed was the ease with which millions of people could be swept under the rug. I would posit that an ad which showed an ultrasound of a fetus followed by the sight of some blood and indistinct ground-up gore running down a drain would be more horrifying than the type of graphic ads discussed here.
On a related note, compare the shower scene in Hitchcock's Psycho with scenes from more recent slasher flicks. The latter are far more graphic, and yet the former is far more effectively horrifying.
