Wow, are you naive or simply uninformed?The author is not referring to himself as Esquire. In the United States, Esquire is mostly used to denote a lawyer in a departure from traditional use and is irrespective of gender. In letters, a lawyer is customarily addressed by adding the suffix Esquire (abbreviated Esq.), preceded by a comma, after the lawyer’s full name.
Uninformed. Thankfully I have very little experience with lawyers.
