Why would it be?

I live in a red state in the South. I'd say about 2/3 of the women I know well enough to be confident of their politics to that degree of detail would describe themselves as both feminists and anti-abortion/pro-life.

If you want to put a name to it, they're basically second-wave feminists with a few third-wave beliefs tacked on.

The real lesson here is that politics are nuanced, and the US party dichotomy doesn't come close to covering it.

I consider myself an AnCap (shocking given my username, I know), but grew up here surrounded by Republicans. I fit in well enough overall because this is where I developed my "social mask" in the first place. I lived in a community with nearly directly opposite politics (Charlottesville, VA) for a few years and found that I fit in pretty well with that crowd as well.

I share enough with both parties that I can have conversations on things that I agree with them on and connect to the point that they assume that I'm "one of them". Invariably, once conversation turns to other topics I'm accused of being a member of the other party. It's to the point that it amuses me when it happens, and I frankly enjoy being in a place where I can connect with most everyone and serve as a sort of translator: I've spent enough time "in enemy territory" from their perspectives that I can explain the other side's position fairly and with empathy while explicitly not holding that position. It makes for stimulating conversation with little risk of offense.
