SEPERATE AND UNEQUAL. To follow up on my general concerns about federal rules intended to make single-sex education more common, Brad Plumer cites the details of the ACLU's suit against gender-based education in Louisiana, which persuasively cites evidence that this education reinforces gender sterotypes. More concerns expressed here and here. I also agree that it's important to make distinctions between K-12 and higher education here; unless the programs involved are very specialized (like VMI), having single-sex univiersities is much less likely to foreclose opportunities for women than single-sex high schools.
