Ah now you are getting into regional dialects and regional slang...That's why when I started the thread I just listed "Country" and said not dialects. Every country has dialects, and the older ones some of the worst. Just like there is "Proper" or formal language for each language, the dialects and regional differences and make even natives of that country confused! (Take Sicilian for example. True Sicilian can hardly be understood by Italians from the North or even mid regions). Here in America we might just pronounce a word differently (Bostonians dragging the Aaaa out in the Paaaak the caaar) or southern's with a distinct twang, etc.
But in like Italy, the Sardinian's and southern regions (Naples, Calabria, etc) have very old and complex dialects that can be near impossible to understand. This is true also in some of the Eastern European block countries, (Georgia, Romania, Czech, etc). And don't even get started on the Oriental languages...There are so many regional dialects even within the same country it can be nigh impossible for a Korean to understand a Vietnamese, etc.
It would be like here in America if one person said "I parked the car" and someone else from another state said "Car, stop, move, stand." or worse, it was just gibberish to you, with no discernable words.
So English speakers have it really easy. (Old Gaelic and Celtic sound nothing like "Proper Queens English" or "Formal American English")
So yeah, just comparing regional dialects is like comparing apples and oranges. That is why I just said "country" in general.
Oh, and as far as "hating" an accent. Hate is such a very strong word, filled with alot of misunderstanding and closemindedness. I can see someone not "understanding" an accent or even not finding it pleasing, but to just tell someone you don't know... "I HATE the way all people of your country sound" is just rude.
Also I have never found someone (male or female) who has just run off with someone because they think an accent sounds 'dreamy'. But then again, as I often point out, I am probably older than 98% of you, so all my teen/young adult ::::squeeing:::: was done long ago and I grew out of it.
Warmly,
