In the past, I had the sense that, politically at least, there was quite a lot of talk about opposition to abortion, but contraception was by-and-large acceptable. When I noticed more anti-contraception talk, I had a vaguely formed notion that this was caused by drift having to do with the difficulty of opposing the legal underpinnings of Roe v. Wade (concerning abortion) without also opposing the underpinnings of Connecticut v. Griswold (concerning contraception.)
But, the Slacktivist has another theory.
White evangelicals have begun adopting Catholic language and Catholic teaching regarding contraception. This change has not occurred due to any new theological or biblical understanding, but due to a political change — due to white evangelical opposition to President Barack Obama.
Whether that’s true or not, I think there is a largely unstated desire among both groups that, as Libby Anne suggests, sex have consequences. If true, I don’t know whether that desire comes from Augustine or Paul or God or what.
Politically, I think that highlighting the overlap between those opposed to abortion rights and those opposed to pro-contraception measures is ultimately a losing proposition for the pro-life movement. Broad support for contraception isn’t going anywhere. And, to the extent arguments against legalized abortion also apply to contraception, those arguments will become less appealing to the voting public.
