Checkout the independent documentary by Fahmi Redza; ’10 Tahun Sebelum Merdeka’. This documentary features the role of leftists (or socialists) in the struggle of independence of Malaya from the British.
One will come up with a conclusion that the leftist were fighting for egalitarianism for all races in Malaya. UMNO, then pro-British (and pro-capitalist till today), refused to give equality to all races so that their personal interests (the elites) can be secured. The leftist were ‘exterminated’ under the excuse of eradication of communists. (take note of this!)
