Singlish should not be disallowed in Singapore, as it has, over the years, become an integral part of Singaporean culture. No, it still has not achieved the status of an "independent language", but it is still something Singaporeans and people all around the world associate with Singapore. It is a defining characteristic as only born-and-bred Singaporeans can actually speak Singlish with the proper enunciation and tonality. Case in question, that video about teaching the Caucasian how to speak Singlish. Granted, anyone can say the words, but it takes a Singaporean to speak the "language".

However, there must be a clear divide between English, and Singlish. A lack of this divide would lower the standard of English in Singapore, as when one uses Singlish in an improper situation, such as in essays or in interviews, it just does not say a lot about the Singaporean in general. Also, Singlish could be twinned with the attitude of laziness and apathy. Thus, we as Singaporeans must be able to discipline ourselves and decide prudently when and when not to use Singlish.

English as it is broken is a stellar example on how the effect of Singlish causes English standards to drop. In most examples on fail English in Singapore, there is the influence of Singlish. Once again the importance of separating E from S is shown.

Thank you for listening to my ranting :D
