Why would a naija man not want to comment on a Nigerian woman's beauty?

Before I start, I’d like to say that I don’t know what “naija” means, so I really, really hope it’s not an offensive word. If it is, please excuse my ignorance.

I was looking up information about gender roles in Nigeria (btw, if you know of a good website about that I’d love to hear about it) when I stumbled across this article. The first sentence, in particular, stood out:

It is rare that a review on a subject such as the beauty of a Nigerian woman is written, especially by a naija man.

I know next to nothing about Nigeria, so this comment completely confused me. I clumsily attempted to find out what “naija” was via Google, but (probably owing to my poor searching skills) I didn’t find anything. So, could somebody explain why a naija man would not want to comment on a Nigerian woman’s beauty?
I also had another question:

I tried in many way, as usual, to fault her beauty but could find nothing negative in her physical features.

Does he want to find fault in her beauty for cultural reasons or is this just something he does?

Well, I don’t know, but you might be able to get the gist here.

As far as I understand it, “Naija” is a modern synonym for Nigeria (and “naija” = Nigerian) used by some Nigerians as an alternative that breaks away from the colonial connotations of the British-coined “Nigeria”.
