Actually it isn't. Charitable contributions fund family planning and gynecological health services at Planned Parenthood, the agency in question. Abortion services are NOT provided on a sliding scale; everyone who obtains one there pays the same for it, the only exception being victims of rape and incest who may obtain abortions without cost. However, even this is not paid for by PP; that's paid for by a specific foundation set up to cover those costs; people donating to that know exactly what they are donating for. FWIW costs of running a Planned Parenthood clinic would be significantly reduced were it not for the cost of security against terrorists who have bombed clinics and murdered staff. So the only people ultimately hurt by this are poor women who want birth control.
