One of the things that’s best about visiting Singapore, for a Caucasian, is that you are immediately a minority. On the streets, in restaurants (except perhaps in the very centre of the city), and especially if you’re living with friends in a housing development board project, you’re the only white face around.
Every Caucasian should do this at least once. I’ve been here 4 times, and I relearn the lesson every time I come here. White privilege doesn’t exist here. I can’t claim the support of the majority anymore.
This helps to reinforce anti-racism within you, and gives you a fresh perspective on the world. Fighting racism starts internally, within each person. Only when people themselves come to the knowledge that they have to fight their own racism, constantly, forever, will things improve.
For those who can’t come to Singapore (and you should if you can; it’s a lovely place to be and it also is a good jumping off point for other destinations in Southeast Asia and Australasia) try going to Harlem, or Chinatown in your nearest big city. Find a park bench and sit there, and look around you. You’re different from everyone there, visibly. The colour of your skin and your features are not like those you see. Then imagine what it’s like for someone who is not Caucasian but who lives in a town or city where there are few people of colour. It’s the same feeling–unease, a bit of panic sometimes–that you’re feeling.
Of course, being in another culture but one that speaks English (in the main) is also a very good thing. Singapore’s strength is its cultural and linguistic diversity.
