Since talking to the Daily Show host Trevor Noah on Thursday evening about why men are important for the feminist movement, Nigerian author Chimamanda Ngozi Adichie has been trending on Twitter in Nigeria, with reaction to her remarks tweeted over 41,000 times at time of writing.

"Men have to be on board," said Adichie, "because we share the world".

As the author of Why We Should All Be Feminists, published in 2014 and based on her TED talk in 2012 which has been viewed more than 1.7m times, her comments should not be a surprise.

She also touched on the question of etiquette between the genders.

Adichie explained she was happy for people to hold the door for her but hoped "they're not doing it for this idea of chivalry," as it could imply weakness on the woman's part.

However, Nigerian student Tade Derhbi suggested: "Hold the door for everyone. It's plain courtesy".
