The Europeans INVADED the Americas. There were many battles and the Ang Mohs ultimately won and the natives lost. The Ang Mohs therefore have every right to stay on as they battled for territory and emerged victorious.
What's the point of fighting a war if you don't get to keep the spoils.
If the Chinks had invaded Malaysia and defeated the Malays, then they could rightfully claim Malaysia as belonging to them. However the chinks, being the cowards that they are, have never had the balls to fight any real battles in order to gain foreign territory. That's just the way the chinks are. They slink in under the radar and hope that they remain inconspicuous while they attempt to become wealthy by cheating and swindling the native population.
If I see a Chink on the streets tomorrow I'll tell him FUCK OFF back to China.
