Oh come on, that's just a ridiculous statement. I have never understood some people's obsession with speaking in "Western" accents.

First of all, can you tell me exactly what an American or British accent is? With the range of accents that it's impossible to say exactly what an American or British accent is.

Secondly, what about other native English speakers like Australians, Canadians, New Zealanders, South Africans? Are you suggesting they don't speak proper English because they don't speak with American or British accents?

English is the most widely-spoken language in the world. When a language is so widespread, it is only natural that regional dialects will develop. Malaysian English (not Manglish) is as valid a dialect of English as American English is. In fact, the many accents in England are the product of many dialects of English spoken throughout the land.

There is no need to speak with an American or British accent, whatever that means, in order to speak proper English.

Thirdly, I suggest you take a look at your own English before saying most Malaysians don't speak English properly.
