The nation’s leading breast cancer advocacy organization confronted the growing furor Thursday over its decision to largely end its decades-long partnership with Planned Parenthood, with rising dissension in its own ranks and a roiling anger on the Internet showing the power of social media to harness protest.
A growing number of religious organizations had become concerned that donations to Komen would benefit Planned Parenthood and had advised members not to give to Komen. Rather than risk offending some donors with a relatively small portfolio of grants, Komen decided to largely cut off Planned Parenthood, Mr. Raffaelli said.
