Many women’s campuses as noted earlier are far from segregated. Several are parts of consortia. Men will be taking part in classes on the home campus and at the consortia campuses. At least one of the colleges also has grad programs, which men attend. Young men can stay over night in dorms at many of the schools.
In addition the women who graduate from women’s colleges, far from being “unhealthy,” tend to go on disproportionately to hold leadership roles in their fields: business, politics, academia, the arts, etc.
