Would the same apply the white southerners with a thick accent who use colloquialisms?
If a person's individual accent reflects their geographic area where they live, fair enough, but when their speech reflects the lifestyle they choose to live, that is fair game to address.
What I cannot understand is why so many Black Americans I have met from the Philly area speak such a perfect English and always dress so properly, it is almost a stereotype to me.
Serious, There is 4 families in my Church from Philly, these women all speak PERFECT English, and I almost never hear any white person speak so clearly and pronounce so accurately, I dunno!
I actually made an experiment once in my home area, when I met a Black person who was openly (exceedingly) kind or appeared very smart, I asked them where they were from. None were from my local area, and 90% were from Philly. (I asked maybe 15 people before I felt I was just being paranoid or something, but the coincidence surprised me. The normal middle class acting Black Americans I met I didn't ask, after all, they acted just like me, and I aint from Philly.)
I concluded it was just something in the schools in their area they grew up in, or, they must have come from devout religious families or something, but I was stunned to my beebers.
SEE? I told you I wasn't from Philly!! LOL!
