How would you characterize lady Macbeth's way of arguing ? How effective is she in getting what she wants ? Scene 7 lines 46-82

L. Macbeth goes straight for Macbeth's insecurities about his manhood. She knows that she can manipulate him when he feels insecure.

What beast was ’t, then,

And to be more than what you were, you would
Be so much more the man.
