Obviously your acceptance of peer reviewed literature is selective. 28 of 37 peer reviewed studies, 76%, in the medical literature show a positive correlation between abortion and breast cancer, yet you only accept those 9 out of 37 peer reviewed studies, 24%, that deny such a link.
You do not take your facts from peer reviewed publications. You simply pick and choose those that support your obvious bias.
Actually when various peer reviewed studies contradict each other, and it does happen, it almost always means the effect they are studying is down there in the statistical noise -- and therefore not a significant threat either way.
