The “all caps” convention the OP characterizes has further evidence in the fact that your name is no longer preceded by Mr. or Mrs. or Ms. on any legal documents. It’s like they are saying you are not a person any longer but an entity. What other reason to leave off the personal identifier? And this has been going on for years so don’t say it is because of the woke pronoun BS we have been besieged by over the past few years.
“Mister” is a maritime title for a midshipman performing a term of endentured service in the navy. Mrs. is the wife of a midshipman. Failing to object to the title of Mr. is another way we fall for their legal trickery. We do not accept titles in America.
