WATCHING THE OLYMPICS I sometimes feel like I’m in a parallel universe, one where women are equal. Or, at least, where no one is trying to legislate our vaginas, though once they did. They (and by this I mean men) thought if we ran 26.2 miles our uteruses would fall out. So, tomorrow as women run up the Thames, past the Houses of Parliament and Buckingham Palace, spare a thought for feminism, this year’s presidential campaign, the ERA, Title IX – and your uterus. This is the year of the vagina when the word – as well as women’s reproduction – has been politicized, but tomorrow at the Olympics as women slog over more than 25 miles it’s clear how far (in at least one realm) we’ve come. The race is a landmark of sorts. This is the 40th anniversary of Title IX, as well as the 40th anniversary of women being able to run the marathon – not in the Olympics itself but in the marathon’s biggest, most important race, Boston. It’s also the 40th anniversary of the Equal Rights Amendment’s passage (if not ratification).
