I think this is very common behaviour among Sporeans who have no nationality awareness. Once they marry a Msian guy/girl, they sing the praise of these people sky high, forgetting that they are Sporeans.
No need to say marry Msian, even buying a house in JB is enough for some to side with foreigners to cheat, harm or abuse other Sporeans for their own interests, no qualms to spread malicious lies and half truths. These are low class scum traitors behaviour. Hope one day they get killed by foreigners themselves for being Sinkie Dog traitors.
