everyone should know how to speak malay. At least communicate effectively among all Malaysians.

Older generation unable to speak still acceptable but younger generation who refuse to learn or unable to string a proper sentence in BM is really inexcusable.

Coming from different mother tongue, surely there will be different accents and slangs. Even a lot of malays also speak with some rempit and wichet version. The standard is BM baku which everyone learn in school.
