Just do an overlay of the number of planned parenthood clinics and the abortion rate over time. They mirror very closely. Why? Because they are the opening pipeline to the abortion industry. But we also know they have a secondary market for dead babies [link].
The rest of your commend is just throwing mud to detract from the issue. The issue is lifestyle abortions. Instead of dealing with the fact that these are the vast majority of abortions and there is no moral reasons these abortions should exist, you try to detract to arguments about contraceptives that are not going anywhere because nobody is taking away anyone's access to condoms, the pill, or other popular non-abortive contraceptives. Did you want to deal with the fact that most of these abortions are without a question immoral lifestyle abortions?
