It had became increasingly difficult to read forums and discussion groups in Singapore without some encountering some kind of passive racism or just outright bias against certain groups of people. Most tread a thin line where religions are never to be touched but you will likely see or hear derogatory references to ancestry, country of origin, skin color or even choice of food!
If it is the policy that you are against, fight the policy on a political platform. Aggression, by any means, just show how ignorant you are.
Let it be known that any form of racism disgusts me. I tend to shut that person off entirely if it is someone I just met or my opinion of the person gets a very big discount even if it is a long time friend. If you had experienced outright racism like I did, you will know how ugly and vulgar the whole affair is.
