By the time the Europeans arrived Singapore had long since declined:
> However, by the time the Portuguese arrived in the early 16th century, Singapura had already become "great ruins" according to Alfonso de Albuquerque.

How far back and how much context is required for a simple narrative to not constitute lying? And for a narrative about national origin, is it not also misleading to insinuate that successive settlements and polities constitute a singular, shared history?
And Europeans were not the first colonial powers to land on and assert control over the peninsula. In fact, the incumbent Muslim powers the Europeans encountered had colonized the peninsula only a couple of centuries beforehand. Aboriginal peoples (pre-history "colonizers") still live in Malaysia, and they're still as isolated and impoverished by the state as they were before Europeans arrived. Malaysia even has its own Plymouth Rock-like monument (on the coast somewhere near Malacca, IIRC), and it's not where Europeans first stepped ashore. And it seems a little odd to presume Singaporeans would identify with the political and social history of their Malay and aboriginal predecessors when Singapore, a majority Chinese community, was kicked out of Malaysia precisely because of racist and xenophobic sentiments of many Malays.
The racial politics of Malaysia and Singapore are at least as complicated as in the US if not more so. I count South Africa and Malaysia as the two countries where racial politics are not only as complicated, but open and explicit as in the US, and like the US the relationship between European colonizers and the "native" groups constitutes only a portion of that complexity. Many other countries have similarly diverse groups, but usually one group is unchallenged in its power and there's very little open discourse about the subject. But contemporary anti-colonial rhetoric whitewashes (figuratively and literally) all of this.
