The speaker of this poem is identified with the poet as the speaker appears to be someone who can understand and knows something about poetry. Hence the poet is admitting before the readers that she does not like poetry just like them.
The word ‘too’ is to emphasize the fact that readers must be in agreement with her dislike for poetry. Also the interpretation that the word ‘it’ used for dislike refers to poetry only is made from the title from the poem, as there is no other thing in the context at the beginning of the poem.
The poet tries to rephrase and in a way veil her words after having expressed her complete dislike for the poetry. She improvises with the thought that even if someone has a perfect contempt for poetry, meaning that even if someone is strongly hating it, still one can discover in something. She gives a break to the line while telling what is it that she feels one with a strong dislike for poetry can still find in it. This is her art of trying to defend the poetry.
The shift of pronouns from “I”, i.e. the poet’s perspective in the first line to “one”, i.e. the reader’s view in the second line is to strengthen the reader’s or impersonal view over the individual view of the poet. The poet continues that someone can still discover something genuine while a poem. The poem was referred to as “it” in the first line is now being called genuine. This suggests that the poet has tried to catch the attention of readers who do not find poetry interesting to take a look at it so that they can find something worthy out of it.
The poet is not actually against poetry as the initial lines indicate. She is indeed of the view that poetry is of such influence and has a substance that someone who is not fond of poetry will also be able to appreciate it.
In short, the poet has attempted to interest the readers who dislike poetry and tried to strike their minds which can certainly see something unusual and informative in any poem that they read. Even if they do not read it by heart, still it will be a good feeling to read a poem.
The poet has in a way tried to win the hearts of the readers who feel that poetry is a waste and it is something that can never interest them. She wants them to see the richness of a poem that can feel genuine even if one is not reading it will complete interest and doesn’t intend to find a meaning out of it.
