History cannot be based on collective amnesia. Malay nationalism is based on collective amnesia driven by taqiyya (deliberately lying) and kitman (lying by ommission).
By definition on Malay, all Malays are Muslims but not all Muslims are Malays.
This is an example of collective amnesia.
Only Muslims born in S’pore or the peninsula before Merdeka or their descendants are Malays, according to the Federal Constitution.
Who was the first M’sian up Everest? Moorthy, an Indian Hindu or Mohd (Moorthy) a Malay and Muslim?
