How many people do you imagine that Melinda Gates is forcing to do anything?
Forcing other people through government extortion. If she wants to finance the "poor" so they can eliminate their unborn succubi, more power to her. If she thinks her "leadership" should be used to force others opposed to the murder of the unborn is reason to use taxpayer funds to finance murder, well...she's welcome to her opinion, but not others' money.
Planned Parenthood should (at best) be a privately funded organization. They should receive NO public funding. Period. Melinda is most welcome to throw her substantial financial power to support Planned Parenthood. My tax money should not be used to finance any of their activities.
