We have simply asked for the document by its official petition name

No, you have not "simply" done that.

The first email doesn't even mention the official petition name. It asks Press Secretary Redfern to confirm that Florida intends to ban "gender affirming care." Naturally he's going to want to ask what you mean by that before answering your question.

Not answering his question and switching to we just want the document is a dirty trick designed to put him in a difficult situation. He knows you can turn around and basically lie and say that he never answered your question.
