I had never had such problems with racism in Singapore. In fact we have racist jokes for almost every race but we do it in a banter style that it actually bonds us rather than cause riots.

Racism comes due to two things. Character and Improper education on understanding different individuals. Americans used to be like that and they still are abit but most of them tend to accept the difference due to their exposure to individualism and opinions and also maybe becos they are a rojak(those who understand malay should know what i mean.)

Why shall we not propose for a one human race. Solves alot of problems and genetically we have one common ancestor. After all colour and complexion are not powerful enough to determine a race physically as environment plays a strong part in this.
