This well worded write up by renowned author, Chimamanda Adichie will surely raise some issues, but she does hit on some valid points. You might want to question her standpoint however, Chimamanda is known to be a feminist, hence the question "when do you cross from feminity to feminism?", because they are two very different things and somehow the line between them has become very blurry. In Chimamanda's words:
A Nigerian acquaintance once asked me if I was worried that men would be intimidated by me. I was not worried at all. In fact it had not occurred to me to be worried because a man who will be intimidated by me is exactly the kind of man I would have no interest in.
