Who is ULTIMATELY behind the mass murder of babies?
The Devil, of course.
Who is ULTIMATELY responsible? The individuals who have abortions, perform abortions, abet abortions and those who provide the legal and political framework in which the death mills can efficiently carry out their work, which is to say, individuals, and the nation as a whole.
You have made up your own definition of genocide. Abortion is an individual decision. The Devil doesn't make you do it.
