I think I was warped for life on this subject by early exposure to the movie version of Anna and the King of Siam. Well I got a double dose-- book AND movie. It's a classic battle of male and female curmudgeons who actually respect and adore one another in certain ways. The King says of Mrs. Anna, "You are a very difficult woman!" Of course they both have to bend a little to learn what the other has to give them, but they remain difficult to the end.

Anyway, a powerful woman who is opinionated is, when not called a bitch, sometimes called Difficult.

In some parts it is said "He (or she) has strong opinions." (And often a gun in the pocket as well.)
