We're never going to convince people who aggressively advocate that killing their own children before they're born are under the influence of evil forces (Satan, etc.).

Many of the pro-abortion people have been fooled think they're doing good work.
They laugh at any talk of Satan.

“If we really care about women, as we say, then we should be telling women that the best thing they can do in their entire lives is to be a mother,” Ms Greene said.

“Being a mother is the greatest thing I’ve ever done in my entire life, no matter what I’ve been doing all my life,” she added.

This is where the emphasis should be placed.

Although... If I was asked to create a campaign to rebutt the pro abortion protests...

Then I'd commission a dozen or so high-quality silicone African American baby replicas.

Then have the silicone replicas moulaged into high quality gruesome abortion replicas.

Hire some black men's and women's former college basketball players (recent graduates, early-mid twenties age) to act as family couples.
Pushing strollers containing the remains of the moulaged aborted babies.

Have them wear a white t-shirt that says, "YOU NEVER HAD A CHANCE TO MEET SOME OF MY FAMILY"

Let's see if these demon-possessed pro abortion fanatics would attack young black couples (who tower above them).

Maybe we could get some footage of enraged pro abortion radicals ripping/throwing bloody-dismembered black baby parts out of a stroller.
