Sanger looks good by comparison.
The problem is that those later quotes, advocating forced abortions, were printed in a periodical owned and edited by Sanger.
If she had been so very opposed to abortion, why did she repeatedly publish articles calling for its legalization and coercion?
Sanger was only opposed to abortion for medical reasons. She was pragmatic; it hurt women because medical science had not yet advanced (still hasn't) to the point that abortions were safe.
However, there is absolutely no evidence that she had any philosophical opposition to abortion whatsoever.
There are many websites devoted to exposing Planned Parenthood's history and roots in Sanger's eugenics obsession. Sanger's quotes are easily found via internet searches.
