How to write a poem when you are so angry that you would rather not

There should be a rule that says that no one under any circumstances should be allowed to write a poem when angry. Poems should be created when the poet is under the influence of joy and bliss. Anger will taint a poem forever. A poem is not where anger should dwell and be allowed to swell. But poets are human and err like everyone else. Why not give them a venue to vent and manage their resentments and or annoyances. Do not we need as a society to ignite the idea that anger can be channeled through writing about what infuriates us instead of caging the rage like a wild animal?

I propose that we allow poets to craft their poems of fury using a certain format. So here it is:
Poems of wrath must not use profanity. They must not slander anyone. However, if the dander is so intense that it is necessary to madden the crowd about the issue and hang the culprit responsible for the accumulation of said antagonism, then by all means the poet may show his rage. However, it is advised that this type of poem not be published to avoid any issues of liable or possible law suits.

Poems of anger should provide the reader with at least four powerful images. It must include at minimum two hyperboles. The poet will ensure that nothing rhymes. Slang will be accepted. The poem should not be any longer than twenty-one lines.

Depending on the level of anxiety or frustration the poet possesses during the writing of the first draft of the poem, it may be necessary to deflate some of the exasperation by taking three deep breaths each time a very dark image captures the imagination. Pilates are also a good way to calm down and get rid of stress.

Poems of sheer ire must be filled with onomatopoeias to illustrate the explosive nature of the fury. However, avoid repetitions and redundancies. I will tell you right now that you will not get any sympathy from me.

By all means use as many similes as you please. Make sure that the meter is just right. Rile up but keep the flow. Use symbolism sparingly. Now if during your pre-write, free write or brainstorming session you realize that whatever it was that made you angry is not such a big deal after all, then write a poem to the contraire. And if my suggestions aggravated you more, then please do not write a poem about me. I was just trying to help.
