Before people join the bandwagon to hurl stones at those people who are feminists, I believe you should research the history of the movement as well as the motives and also note that Chimamanda Adichie is only one voice among others.

Let me get in into the specifics.

What is feminism and why has it become popularized now?
Feminism is a gender movement that advocates for the recognition of the roles played by women in the society as well as granting them equal participation in every sector of the society.
Everyone knows that the world today is a patriarchal one (another way to say that "it's a man's world" and this has always been from history. Women, before the 20th century, have always been disenfranchised in terms of political issues and deprived of their fundamental rights of voting and being voted for. Check out the pre-colonial igbo society where a girl child was considered only useful for the husband's house and not to ever go to school. Women have been deprived of basic rights such as ownership of land, ownership of her will after her husband dies. The girl child is the weaker one who has been dominated against her will in the society and for a long period of time, Society has been cool with that while these women died inside.

Here comes the feminist movement which began officially in Europe but had already started unofficially within numerous places where certain women chose to fight against injustice meted against them. The new wave of feminism fought and guaranteed the rights of women to vote and be voted for. It guarantee their rights to own anything that actually belonged to them. With the new wave which found expressions through novels, public protests etc, the public began to recognize that the fact that something has been the norm does not mean that it is right (case study of the Twins killing in calabar). That the girl child did not protest when been bethroted to her husband does not mean that she was happy with the decision and the fact that a woman recieves her salary at work and gives her husband does not mean that it was done out of a willing heart.
If it was done out of a willing heart then feminists have no qualms but the fact is that most of these women fear the reprisals that they would face at the hands of the society, some churches and also their families.

Please dear critic, understand that the true feminist does not wish to demean any gender but ensure that equal rights are granted to both. The trend in the world now is that there is hardly equal pay for women and men alike in the same position and in most cases there are bottled up cases of sexual harassment which the women are afraid to speak up against.
Sadly the only way you can get Nigerians to understand the gravity of an issue is when you forcefully bring them into the narrative so here goes,

Would you prefer you daughter to be known as someone bred to become another man's property in the future or as a unique person herself who should be comfortable if she does not marry?

Would you prefer that your daughter remain in a marriage where the husband beats her to the brink of death each day and yet she remains there because she is trying not to offend the pastor or maybe afraid that Jesus will banish her forever if she does seeks for divorce?

Would you want your daughter to keep mum (silent) over things that have happened to her like sexual abuse like rape and harassment (perhaps someone just randomly smacks her in the bum just as it happens in the public)?

Would you want your child to be deprived of something as happiness just because a culture of bride price in place which chases away her fiance?

You want your daughter to aspire to become anything she can be in the world abi?

You want the world to be an environment where your girl can say what she wants and associate with anyone she wants (after you have trained her well) right?

If you desire this, stop throwing stones at the feminists and join them in advocating for a better world for the female child.

And please do not pay attention to those radical feminists who advocate that #men are scum. They lack the history of the movement and anyone who does not learn her/his history will be consumed by the raging inferno that comes along
