I don't think it's fair to say there's really an overarching strategy here, certainly not between the people placing abortion clinics & the pro-life crisis centers. Different goals.

Abortion clinics are "strategically" placed where there are large concentrations of people who need their services including sexual health care, contraception, education, and yes also abortion.

Who needs this discounted health care? That means poor people.

Who needs abortions? That means unwanted, out of wedlock pregnancies. Which also means poor people

That means an urban environment.

And urban poor happen to be black.
