Almost never talked about is the uncomfortable alliance between right wing Protestants and Catholics. We all know the Protestants showed up late in the anti abortion game. Both thought they could gain more than the other by teaming up. The truth is they have little in common.
Catholics claim their stand on birth control and abortion are based on theological principles worked out over hundreds of years. Though many of us roll our eyes at these ideas we all have to admit they are older and more comprehensive than those of conservative Protestants.
Conservative Protestantism was in favor of abortion only a few decades ago. I grew up in a conservative denomination and that denomination at that time favored abortion rights. It has always been my impression being for abortion rights back then was because Catholics were against it.
Eventually, TV evangelists saw money in being anti abortion and things changed. If there is more success in anti abortion court rulings or laws I am certain we will see split.
It will come about over punishment of women. The Catholic position has been carefully crafted to avoid the political pitfall of sending women to prison. It has a theological position that the woman is hapless and cannot be held responsible. The Church cleverly claims this is a legally defensible position. It has never explained how it would be defended.
When the angry Protestant religious right demands punishment for women Catholics will lose on abortion.
