Between January 1970 and October 1974 they staged numerous protests, the first of which was lodged against the Nyenrode Business University, which did not allow women to enroll at that time.[69] In 1970, they led a protest in Amsterdam to address anonymous groping. Sitting on parked cars and bikes, the demonstrators whistled at male bypassers. Entering bars they pinched the buttocks of male patrons to emphasize their objectification.[71] Other actions in which they participated included protests for day care centers, reproductive rights and women's toilets in public spaces.[72] After 1972, most of the Minas protests were focused on the issue of legalized abortion and their most successful campaign was called Baas in eigen Buik (Boss of your Belly), which argued for women's right to govern their own decisions regarding their bodies.[73]
