So it is not suprising to find in some areas, women only do the small things for their tribe like in Bataknesse. But in native Indian, women appear as a female ruler because it was believed women have greater strength than men.
Gender differences appears to be a problem when discrimination based on gender happens and as we know, women who become the main victims of this. Women experience discrimination in many ways. Besides that I already mentioned above, women also suffer from slavery, violence, sexual harassment, discrimination because patriachy system, religion, differences opportunities to working and lead an institution.
Discrimination on women in many countries appear at the time colonialism come. Before the colonialization -countries that have indigenous tribes like Indonesia and America- women have an important role in tribal life. Not only as second class citizens. Most tribes hold matriachy system. Properties belonged to women and when a man married, he must stays in his wife's house. But it changed when colonizer bring their culture, effecting it and change the social system to be like theirs or as we know, patriachy system. Women began to be marginalized through a variety of restrictions to the social accsses.
Sexual harassment often experienced by women. But the saddest part is when the rape victim also has to take the blame. Women often blamed for dressing "sexy" so they provoke men to harass them without seeing the men's factor. The things above are the external factors (outside the woman's own personal) that cause discrimination. .
There are also internal factors that come within women themselves which is supporting the sustainability of this discrimination. Women feel lack of self confident that they feel they can't work things out. They receive point of view that women being created as the second class citizen. However, the most dangerous is when women feel comfortable with this system of discrimination and they feel no need to defend their rights that have been violated.
