No, it’s not subjective and it’s not about being superior. I was COMPLETELY baffled by my husband’s speech at times early on - had no idea what he was talking about (”let” vs “leave” with the dog outside....picture that). Rules and structure are important IF WE ARE TO COMMUNICATE. Otherwise it’s the Tower of Babel, might as well be truly different language.
One will NEVER learn that “structure” in proper English class or the handbooks used. Doesn’t matter where the class is or from where the teacher hails.
Even my husband knows it’s not proper, so does not WRITE it. He speaks it, but it takes a special stubborn ignorance to make the effort to write/type it!
Dollars to donuts you won’t hesitate to criticize “ebonics”, common black speech patterns. This is the same thing - bad grammar (NOT pronunciation/accent - that’s much different).
I have lived all over this country, and anyone who thinks one area has far worse communication than another, is just living within their own biases.
I was born in the south, have family in the deep south. I currently live in PA, I have lived in CA, I have spent a lot of time in the midwest, and NY... about the only major parts of the country I have not spent good amounts of time are the rocky Mountain states, southwestern states, and New England.
Everywhere, and I do mean EVERYWHERE, I have been, they all have their distinct enunciations, and language. It doesn’t take long to figure out what’s what, whether it be, how they use, or refuse to use the “be” and its conjugations... How much or little they drawl etc etc.
Yes, it can be amusing.. and being a southerner I still enjoy being able to use bless your heart as an insult, and getting thanked for it by folks who have no idea they are politely being called an idiot.
Yes, it can be disconcerting to first hear another accent or different way of speaking, but I’ve never not been able to rapidly comprehend someone regardless of those types of things, no matter where in this Country, or even other countries that I have been exposed to. Want to have fun, hear some of the colloquial ways English is spoken in parts of the UK.... You think US dialects are confusing you wouldn’t survive there... In a country a bit over half the size of California, the variation of the language is crazy.
Still, language is fluid.
What is considered ‘proper’ today will not be a hundred years from now.
Can two ebonics speakers understand each other?
Can pidgin English patois be understood?
