I have an axe to grind.

Great anger is more destructive than the sword.

Bee in her bonnet.

Fear is a fine spur, so is rage.

Sticks and Stones may break my Bones but Words will never Hurt Me.

Anger can be an expensive luxury.

Angry Men Make Themselves a Bed of Nettles.

Where there is no antagonist, you cannot quarrel.

Least said, soonest mended.

Anger is as a stone cast into a wasp’s nest.
