Let's be clear you want to go there. This is how your false victimization always starts. You go out of your way to mush people to let your presence be known. Then when you're corrected with facts, and get clowned by the entire NT community for the outlandish things you say you act like a victim.
Along with communication (social sciences), I've also went to school for television, radio and film.
Accents are learned behavior. A positive response in communication acts as a reward. As I stated, before social media, when people traveled to other parts of the United States people knew you were a "New Yorker" by the way you talked.
...it became marketable in the 90's during Hip-Hop's industrialization. The generation before us Millennials, Generation X, was the most notorious for exaggerated accents.
In a radio course, you're actually trained to adopt the accents of the region you're catering to and exaggerated them.
However, since the rise of social media and video services like Youtube we get a wider spectrum of regions and cities and see not everyone has an exaggerated accent.
Dialect and accents are two different things. You're from Argentina and fiercely defended your heritage in a thread , where you said you "go out of your way to speak in Spanish".
Now did people in Argentina say things like "B", or "yo" which you flagrantly use on NT? That's dialect! Not an accent, more over it's what they call ETHNO-LECT, African-American Vernacular English to be exact.
If I go to Compton, there's slang that certain communities would understand there and across America. The way they say it is an "accent". Which is learned behavior.
If you've ever been, there's females that sound like they're from the "Valley" or speak in "correct" diction. The hood "accent", is learned behavior.
Again, like you and Ninjahjood, who've valiantly fought for Latino-America and to make sure you were separated from BLACKS in every way including language; you LEARNED to talk in AVEE. It isn't native to the Dominican Republic or Argentina. It's not how your parents talk either.
Like I stated, and you stated when people mistake you for Middle Eastern, you OVERDO your accent...not dialect.
