Are race-based political parties still relevant?

I had to beg, borrow or steal graphics to help put my point across:
From Malaysiakini:

I am interested in the pie-chart which shows the racial composition of the three major races, which roughly reflect the situation nationally.

This clever use of the Rubik's cube by the creator of the graphics, put it succinctly, the effects of the race-based political parties like Umno, MCA and MIC, on the people, over more than 50 years.

How can we ever get rid of racism, if we continue to harp on race when dealing with everything from education, employment and business? It is like looking at the pie chart showing the composition of the races, and asking for national unity.

The Rubik's cube (above, at the beginning), reflected more like what students felt before, in the fifties and sixties. Since then, politicians had made it worse.

If the intention is to separate the races, then please, do not call for national unity (illogical to me) and wonder why racial polarization is getting from bad to worse. At least, Pakatan Rakyat has given us some hope for improvement.
