"You missed the irony in the previous statement "
No, I considered the previous statement very carefully. "In" would have been ironic but "into", being a different word, must mean a something different so I rejected the possibility of its being ironic.
Using the correct word is essential if you want to communicate what you mean. If you don't use the word that expresses what you intend to say you end up saying something different and should not complain if you're misconstrued as a consequence.
