Tuhia he haere tonu mo tenei whitianga - I te Hui-tanguru 1974 ka wehe atu tetahi roopu o nga mema o mua o MAS ka hanga i te "Movimiento de Liberación de la Mujer" (MLM). Ko nga mema tino kaha o te MAS kaore i uru atu ki te MLM, i whakauru i nga pakanga akomanga ki te pakanga ki te sexism. Hei whakawhānui i to ratou mema, i hiahia ratou ki te awhi i te whakamāramatanga whānui ake o nga take wahine, engari i roto i te tikanga, he rereke te painga, i te mea i hangaia nga roopu iti o te hiahia i roto i te whakahaere hou e arotahi ana ki nga whaainga motuhake. I mahi ngātahi ngā rōpū iti i runga i ngā take pēnei i te materoto me te mahere ki te manaaki i tētahi hui whakahē i te Huihuinga o te Ao mo nga Wahine
i whakahaerehia e Mexico i te tau 1975. Ko te whakamahere o te huihuinga ano i hangaia e te huihuinga a te UN, a, ko tetahi atu wehenga i puta, i te wa i wehe ai tetahi roopu wahine ki te hanga i te "Colectivo La Revuelta" (Collective Revolt) me te kaupapa o te whakatu i tetahi maheni hei hora i o raatau whakaaro mo te nekehanga. I haere tonu nga mema o te MLM ki te whakarereke me te whanake, me nga roopu e wehe ana penei i te "Movimiento Feminista Mexicano (Movement of Mexican Feminists, MFM)", i te 1976 i noho hei mema nui o te Coalición de Mujeres Feministas (Coalition of Feminist Women, CMF). I arotahi te CMF ki te whanautanga o te whanau me te tutu ki nga waahine ka tiimata ki te whakatu i nga whare tiaki wahine. Ko te "Lucha Feminista" (Feminist Struggle), i whakatūria i te tau 1978, i huri hei "Frente Nacional por los Derechos y la Liberación de las Mujeres" (National Front for the Rights and Liberation of Women) i roto i te "National Front for the Rights and Liberation of Women" (National Front for the Rights and Liberation of Women).
