I dint knowhow this idea got propagated through time but, this is defined by the changes in civilisation as man continues to advance with the most civilised societies looking down on the less civilised individuals from a different race like savages. Its just bad and shows how little they know of there bodies than is reflected in there civilisation.

The idea that a race us superior to another race is a sad way to think.

I won't blame the government not to be doing enough. I think the government are doing just fine in trying to eradicate racial segregation from societies and its left for every individual to be receptive of the idea and change for good or we watch ot die with time.
