Why are there no diversity or racism issues in Singapore?

There are no other races in Singapore. They are all Asians.

There are no American liberals stirring the race pot in Singapore. If they did, they would be arrested, caned and jailed. They can 'bravely' spout off in America because they have laws to protect them. The cowards can't/won't hide behind the law in Singapore.

Because they punish with caning the bare butt.
