"Strong" female characters

What a load of hooey. If you watch a lot of DVD extras, I'm sure you've noticed that every single actress who has ever been interviewed has described her character as being strong. If they're especially obnoxious, they'll probably also say that you don't see many strong female characters in movies. But if you don't see many, then how come all of the others are also calling their characters strong? What is that supposed to mean anyway? Do they think they're doing something to fight sexism by playing a "strong" woman? I've never heard a male actor call his character strong. Not even Arnold.
