Planned Parenthood is an activist pro-abortion organization. No matter which side you're on yourself, you're stupid if you seriously expect that someone who strongly opposes abortion should support PP, and the government should fund PP, because PP spends less than 90% of its budget on abortion and does many other worthwhile things. That is not how human behaviour works. It's like saying someone who supports GLBT equality should support the Boy Scouts of America, and the government should fund BSA, because BSA spends less than 90% of its budget on discrimination and does many other worthwhile things. One showstopping issue can and routinely will override others; that is what "showstopping" means.
Both sides of the abortion debate agree that abortion is a matter of overriding importance, something that really matters. If abortion didn't really matter to Planned Parenthood, then PP could and presumably would forget its abortion advocacy and have a lot more support for its other activities. Since they don't do that, their opponents should be expected to similarly treat the issue as important. That is basic human behaviour, and anyone who can't form and act on reasonable expectations about human behaviour will certainly lose in any effort that involves human beings, regardless of the moral high ground they may think they stand on.
