Only very sick liberals, with hearts of stone instead of flesh, can.
If more ordinary liberals were actually exposed to what goes on in abortion mills, they might change their minds.
The regular use of ultrasound is already moving more and more young people to the pro-life side, even to the point of participating in the March for Life. (If there were only something to move young people away from support for “gay rights”, too!!!!)
There is no such thing as “ordinary” liberals. Those are misinformed or indifferent people who would not be liberal if they knew anything.
