As I said to David above it all depends and the issue is very specifically and directly nationally and Leader 'power'. I will vote I am sure but I do separate for whom as an individual.... and not forgetting that the DA, like the ANC, uses the power of 'the Party and Party Lists' rather than constituency support. 

I wonder Rodney where you are coming from too, saying 'Zille may not be a racist'... as opposed to isn't... are you saying she might be? though I do agree she, and Maimane should stay off Twitter and the like (you do include him too I suppose)
On colonialism, you seem uncommitted as to whether it had any benefits or not. Obviously it set some basis for good governance and infrastructure regardless of whether it was universal. I would submit the vast majority of our citizens cannot define colonialism and you are being presumptious! 

Where do you come from in SA.... Cape Town and the W Cape... or up north where you have aspirations rather than something more concrete?
