I think it's interesting to see the framing of this- the idea that men might not be allowed to vote over something happening to women's bodies suggests that everyone is in agreement the abortion referendum is about something happening to women's bodies.
Trust me, the issue in Ireland is not predominantly about controlling women's bodies, in the way I think it clearly is in parts of America. The majority of people here were raised to believe life starts at conception. I absolutely believe there are people who want to exert control over women's reproductive freedom for purely misogynistic reasons, but they are not the main voices in this. I have had discussions with many female friends, including mothers, who have said they still believe this- the ones I know will vote to allow other women to make other choices, but fundamentally believe that there is a life there before birth.
This is what the abortion will be won or lost on. There is no moral capital to be made on 'traditional' issues around contraception, cohabitation, divorce anymore. It's just this one left standing. And that's because for most of the electorate, it isn't about women's bodies, it's about the question of at what point the women are carrying another life and what our responsibilities to that life are. In which case, why should only women get to decide on a huge moral question like that?
The leaders of the pro-life movement here are female, believe it or not I know ordained clergy with more progressive views on abortion than the women leading those movements. They are currently using victims of rape, and women conceived by rape, in their arguments. It makes no sense, but many of them argue that women will be forced into abortion without a law to protect them and their unborn children.
In so far as this is clearly a feminist issue, it does have wider dimensions and those are the ones it will be fought or lost on.
