But, Poetess! What if I realize that I've made a mistake in my critique? What if I realize that when I read the poem initially, I completely missed the point, and the poet points out that my critique isn't worth jack? What am I going to do about my injured pride? SHOULD I DEFEND IT ANYWAY?
Re-read the poem with what you now 'know' in mind. Is it honestly obscure, or
did you miss the point?
If it's honestly obscure, be ready to defend your critique with examples. "Oh, I see what you're saying, but the imagery in the second stanza misleads the reader to think something else entirely and that last part seems out of place for that interpretation" is a lot better than "no, I'm right."
If you just missed the point, be ready to either admit that nicely or bow out. "Ohh, I see that completely now. Oops."
On a personal note, I've written poems that seem to communicate -- people would pretty much say exactly what I would if asked what it was discussing -- yet that someone else would find an entirely separate (legitimate, or at least definitely supported) interpretation of.
In
that situation, I sort of chuckled, "Oh wow, yeah, that totally does fit, too. Not what I had in mind when writing it, but yep."
