This is a really extreme example of something Ive noticed lately about accents transcending languages. Like people have a tendency to maintain certain aspects of accents even when speaking a different language than where the accent derived from.
For example, the new pope yesterday speaking Italian still had Chicagoan inflections when speaking Italian. I once dated a girl from South America who was ethnically entirely Italian, and she spoke Spanish but with a northern Italian accent. Her Mom did too but it far more noticeably.
Rural American people completely ignoring the pronunciation of Spanish words and having thick drawl is virtually the same thing, but stupider
You know things are bad if the Catholic church is a last bastion for progressive social change
