The problem is that you are assuming that concepts such as rights for women are Western values when there are civilizations which had those values before Western societies adopted such values.

Swaziland had polygamy but women in Swaziland also had more rights than they have now after being colonized. That's why women there are trying to restore certain rights for women. As for Guyana, the African villages which emerged after slavery ended operated their own system of government which was independent of the colonial administration. It makes no sense to attribute voting rights for women in those villages to Western suffrage movements for women when the villages in Guyana had women's suffrage decades before Britain did.

It was the traditional customs that Africans in Guyana brought with them that gave women the right to vote. They came out of African societies where women had a voice in politics as opposed to the West in which women could not vote at the time. The fact that you are trying to assign the structure of African villages in Guyana to Western culture is typical of the type of Western arrogance I have to deal with regularly. You don't even know the history of the African villages in Guyana but you are trying to give credit to the West for them.
