text: Yeah ... I was wondering about my punctuation there :-) I am well aware of the history. 
  Perhaps to be more specific for any future readers. "the so-called "coloured" peoples; the Indian population ...."
  
  I could also have said: "And of course there are other very large cultural groups that you do not mention: the so-called "coloured"; the Indian population who arrived here as either slaves or indentured labour." But that sounds a little clumsy.  And I only had limited characters!
  
  I'll have to update My Grammarly. https://www.grammarly.com
  
  One would hope that readers of the DM would be aware of the history but my question remains: "And how will you change it?"
