And I think you've missed the point. 

The above advice is a good way to ensure you get to say what you want to say. For the most part people listen to other people who sound like they have something to say. And I dare say I (and other 'males') have listened politely and respectfully to women who do that. 

And you shouldn't belittle yourself by saying, "I haven't seen it . . . but it sure must happen". It's a good way to get yourself not-listened-to.
