I believe that there are gender roles; however, those gender roles are not to be static, but flexible; and neither should gender roles be prisons and neither should they be forced. Gender roles are determined, imo, by the needs of the society in question. In our current society, with our survival needs cared for through science and technology, there is little need for gender roles. Go back 6,000 years and the male's greater, natural, physical strength increases the liklihood that the man could defend the tribe and bring home the successful hunt; and the babies required nutrition from the breasts of women as there were no other viable, known options. Thus, these traditional gender roles were important to the survival of the family and the tribe. Today, all that's needed to put food on the table is earning a livelihood, creating the need for the another to care for the children. Both genders are equally capable of performing either function in our day and age, thus the gender roles change or disappear as the need is no longer there.
