I think you're talking about one of the perceptions of modern, post-Romantic poetry, which is that poetry somehow arises out of emotion. Thus people who are, for instance, grieving or in pain, or excited about their new dog, tend to gravitate to this art form. Because of its shortened form, non-epic (i.e. lyric) poetry does lend itself to the showcasing of emotion, but what I think of as the Romantic Mistake says that this emotion must be your own, must be somehow drearily confessional. Classic lyric poetry is as much about a constructed persona as about the elegant structure of rhythm and meter.

Most of my favorite poets were dead by the first century C.E., however, so don't listen to me. The English-writing poets I do like learned all their lessons from Catullus and Horace anyway. So I think what you are saying is not that you don't like poetry, but that you have no patience with confessional poetry.
