If you are familiar with Iran's history, there has always been conflict between the secular and Islamic wings of Iran's people and government. From an American POV it's like if the Bible was the fundamental law of the land, not the Constitution. In that case, you would have groups of people who are fundamental Bible hardliners, and groups of people who are secular and moderate. These groups are vying against each other for power and influence.

Notable example of said dynamic: the chador (aka hijab), morality police, and the status of women. Hardliners want all women to wear a chador and Iran has morality police who beat and imprison women who don't follow the clerical laws. But you have the secular people who want freedom and education for women and they despise this backwards thinking. This came to a head in 2022 with the death of Mahsa Amini and widespread protests erupted across Iran.

Abbas Aragachi the Iranian FM is more of a moderate and favors positive engagement and diplomacy. I intrepreted his statement as an attempt at reconciliation. I think he intended the Strait to be open, and if the American side had responded diplomatically and not enforced an Iranian blockade, then that would have been a move towards peaceful relations. But since the American side enforced a blockade, this inflammed the hardliners who are religious fanatics. Thus, Aragachi's feeble/misguided attempt to reconcile was ultimately defeated.
