I see what you mean...
Rants are common in teen poetry, which I'm very sorry to say. These rants often discuss issues of broken hearts and lost loves, suicide and unhappiness...the usual stereotypical teen angst. I see why you would worry about the writer more than the poem. I try to avoid all rants in the poetry forum when possible. Poetry should have emotion within the words, however the words should not be the emotion. For example, one stroke on a canvas cannot say "I'm happy because my boyfriend loves me." You cannot expect someone to go beyond in understanding a painting when there is only one stroke on the canvas. Sooner or later, the reader loses interest, for what is the artist trying to share? Nothing. However, many strokes eventually form an entire picture that we can enjoy, feel, and understand. The artist is sharing something much more than strokes. okay, that was a not-so-great example, but I tried.
Hey, look! I'm ranting about rants!
People might not realize it, but rants are quite self-centered, and often shows that the poster is relatively lazy. Example: Today, my boyfriend broke my heart because he cheated on me.
Very straight forward, but is it poetry? No. Where's the painted picture here?
In any case, rants are not for the poetry forums. I guess that's why Ron put up discussion forums too.
Apologies for the terribly explained opinion of mine.
