What exactly is wrong with consensual polygamy/polymory etc?
"There has to be a culture change and that has to brought about by policy makers taking a very clear stance on this issue, saying that in this country, one married man is allowed to marry one woman," she added.
Yes there does need to be a culture change, one where women are empowered to stand up to requests/coercion to do something they don't want to do and where everyone is free from religious stupidity. Attacking polygamy is missing the point, the problem of people being forced to do things against their will goes across allsorts of issues. Young men and women forced into arranged marriages, women forced into doing things they don't want to do and children forced to live with the unhappy consequences.
Tackle disempowerment and religious dogma but dictating the way someone wishes to live their life isn't the way to go about things.
Womens rights are human rights. Women should be free to choose how they wish to live. That is the most important thing surely?
