For the good of unity and education of the nation, all Chinese and dialects, Malay, Tamil and Hindi should be banned from TV and radio, only English be used on national media. Those Chinese, Malays and Indians who wish to keep some of their cultural roots can always keep them at their homes and private businesses.
Resident immigrants (not tourists) must pass a basic English test, as has already been in place in US and UK for more than decades. We're not part of Malaysia anymore. We've never been part of India or China. We've never had a common Singapore language except English by which all laws of the land are conducted.
