In my opinion, I do not see any form of malice in her comments. She is not about to kill, perjure or abuse a black person. She just doesn't like them. The same way a lady can say "I don't like short ugly fat men and I have no desire to meet any". Is that really a crime? An unforgivable sin? Yes you might consider such a person shallow but eh. Why is it that the skin colour issues turns the reaction into a frenzied situation?
For me the biggest issue is that Rozanne is a Councillor. Does she represent any Black person in her constituency? What is her history in dealing with these constituents if any? Are the electorate in her constituency happy with her?
With the kind of view she has expressed, I will suggest that public life is not for Rozanne Duncan in an increasingly diverse and multicultural British society. However as a private citizen, I will defend her right to forever have a problem with whoever she chooses. And the law of the land is on her side as there are no crimes for disliking people of any skin colour.
