Strong protagonists

Boudica, one of my favourite characters.

I recently came across this article about the characteristics of strong female protagonists. While I think that the characteristics listed there make great characters, the term 'strong female protagonist' gives me a pause. I'm all for strong female characters. I love them! We need them! But I'm always a little... disappointed when a book is described as having strong female characters. I've never seen it mentioned that a book has strong male characters. And I would say that the characteristics in the article define great protagonists, whether they are male or female.
