In reading about Margaret Sanger (often cited as evidence that planned parenthood has a race based agenda) her work is being taken out of context.
The foundation she helped form had these goals;
At its founding, the ABCL announced the following purposes:
To enlighten and educate all sections of the American public in the various aspects of the dangers of uncontrolled procreation and the imperative necessity of a world programme of birth control.
To correlate the findings of scientists, statisticians, investigators, and social agencies in all fields.
To organize and conduct clinics where the medical profession may give to mothers and potential mothers harmless, reliable methods of birth control.
To enlist the support and coperation of legal advisors, statesmen, and legislators in effecting the removal of State and Federal statutes which encourage dysgenic breeding.
The term dysgenics was first used as an antonym of eugenics the social philosophy of improving human hereditary qualities by social programs and government intervention.
Although it is not a popular idea today, at the time she was forming the collection of thoughts there was little knowledge about diseases and illnesses that afflicted many people of the time. By preventing individuals with diseases or unfit genetics from breeding the plan was to reduce genetic unfitness.
To say that black populations are genetically unfit is your words not margaret Sanger's
Sanger's view of the project termed the "Negro Project";
To give them the means of helping themselves is perhaps the richest gift of all. We believe birth control knowledge brought to this group, is the most direct, constructive aid that can be given them to improve their immediate situation." Sanger viewed the Negro Project as another effort to help African-Americans gain better access to safe contraception and maintain birth control services in their community as she had attempted to do in Harlem a decade earlier when Sanger's Birth Control Clinical Research Bureau (BCCRB), in cooperation with the New York Urban League, opened a birth control clinic there.

It really doesn't sound like she had a twisted agenda.
