malaysiakini on the MORE FUNDAMENTAL CAUSE of NATIONAL DISUNITY?

It is good that some UMNO leaders are considering the causes of the divisiveness that are present in society and many older citizens lament the fact that today after more than 50 years of nation-building, our children do not mingle and interact as freely as say 30 years ago.
It is possible that having schools that cater to different (and separate) races contributes to separate development and therefore lost opportunities to build more cohesive ties.
So this proposal in malaysiakini by Mukhriz: Close down vernacular schools certainly attracts attention especially during the UMNO polls.
To me the more fundamental cause of national disunity is the operation of race-based political parties and I suggest that instead of merely singling out vernacular schools that reflect race-based political realities, political leaders should work out ways to permanently replace racist parties.
