Of Ibrahim Ali, the crusade and DAP father and son apparent weak command of Bahasa Melayu

I often wondered why the DAP lead by the icon of nepotism in Malaysian politics, the DAP father and son tag team of Lim Kit Siang and Lim Guan Eng is gunning for Ibrahim Ali to the extent of inviting all non UMNO BN parties to join the DAP to get Ibrahim Ali.


I think my question has been answered by this video recording of Ibrahim Ali giving a rather rousing "across the entire Malaysian political spectrum and issues" speech:

The speech is in Bahasa Melayu, Malaysia's official Language, I suspect the two DAP Lims command of Bahasa Melayu and its nuances is rather elementary that is why they  misinterpreted Ibrahim's speech and thought it meant to be Ibrahim's call for a crusade against  Christians, which certainly is not the case.

 A careful listen to Ibrahim's speech revealed that he said no such thing, listening to the whole speech, though in his usual agressive style, the gist is that he is not inciting Muslims to hate Christians rather he calls for Malay/Muslim unity. 

So why is the self appointed DAP freedom of speech campaigners wants to now muzzle Ibrahim Ali from saying what needs to be spoken?
