False. Overwhelmingly those who have abortions have used contraceptives. They might not have used them consistently, but they used them and quite often. People who embrace the contraceptive mentality invariably come to “tolerate” or embrace abortion.
They may have used contraception at some time or another, but not at the time they got pregnant. Even the Alan Guttmacher institute, which has a financial interest in underestimating the role of personal irresponsibility as a cause of abortion, estimates that at least 65% of abortions occur because of failure to use contraceptives.
There are also those who do not use contraceptives because it's against their religion, but have no qualms whatsoever about killing baby after baby.
I'd love to see a study examining attitude towards abortion and contraceptive. I hypothesize that the study will show that the stronger someone's "pro-choice" attitude is, the less likely they are to consistently use contraceptive.

Again, not true. Even the pill sometimes fails. What leads to abortion is the contraceptive mentality which reduces children to a commodity.

No, it’s probably the opposite.
