Have enough to combat racism?

I think that there is enough that has been done to combat racism in Singapore as I can see people of different races interacting with each other as an equal in public places. Racism can be dealt with in Singapore by letting people of different races talk to each other and let them understand that there is not much difference in their races and they should not make false judgments on other people's race.
I think in Singapore what has been done to combat racism is to have Racial Harmony Day, it is a day where people of all races in Singapore come together to celebrate. In school, pupils are allowed to wear their own costumes which let people know more about their own race. I think that racism can be dealt with by creating a lesson in school to educate the students more about the cultures of other races.
