Everyone with a half a brain (aka everyone except the anti-feminists) knows that sense the dawn of time, men had rights and privileges. Women on the other hand didn't. Religion came along, and well all religions say that men are above women, women are property , men own women and other things of the ilk. Women were seen as 1) Something for men to have 'fun' with and 2) Baby factories. Abortion was considered bad because she wasn't doing her job as a baby factory. If men were the ones that got pregnant it would have been legal sense the dawn of time, because men had rights and privileges. Religion places men higher than women so it would support abortion also. Not only that, but by the time religion came along men having abortions would have already been set in stone. Because religion would support abortion, religious books wouldn't go about 'morals'. Therefore reasons to be anti-abortion for religious reasons and 'moral' reasons wouldn't exist, which in turn would make 85% of pro-lifers pro-choice.
