Great article. This is it - agree with her or not, these views don't make Kemi self-hating. Nigerians are generally conservative in their views - it's part of their culture. Besides that, she's an individual and can hold any view she believes.
The quote below is from Chimamanda Ngozi Adichie. (The quote is a bit way down the article if you're reading it).
Growing up in Nigeria, I didn’t think about race because I didn’t need to think about race. Nigeria is a country with many problems and many identity divisions, but those identity divisions are mainly religion and ethnicity.
So my identity growing up was Christian, Catholic, and Igbo. And sometimes I felt Nigerian in sort of a healthy way, especially when Nigeria was playing in the World Cup. Then I would think about my nationality as a Nigerian. But, when I came to the U.S., it just changed. I think that America, and obviously because of its history, it’s the one country where, in some ways, identity is forced on you, because you have to check a box. You have to be something. And, I came here and very quickly realized to Americans I was just black. And for a little while, I resisted it, because it didn’t take me very long when I came here to realize how many negative stereotypes were attached to blackness.

There are many more statements like this by Africans in the UK/US.
I have to say that though Chimamanda said she rejected being Black due to the negative stereotypes, this isn't the reason for many. It can be one of the reasons definitely but the major reason is not so much rejection of being Black itself as it is rejection of being forced into an identity you've never held.
Most people know 'Black' is their racial category and they have a passive acceptance of it but to become it? To be expected to state it as though it is who you are when you've always been other things, is like being expected to have "Brown eyes" or "Pink tongue" as an identity. It sounds silly but that's how it feels.
It's a completely different concept for those who've been Black all their lives (and have parents or grandparents who've been the same) - the same way Chimananda has been Igbo (her ethnicity/ethnic identity) all her life.
Sadly, she too was harassed as 'rejecting her Blackness' or self-hating by some people for saying such things.
