Here's what you said, Morris-ey:

"For every black person who is not offended, there is one that is and probably twice that number of white people taking offence on behalf of black people."

You are accusing white people of taking offence on behalf of black people, in other words going all sanctimonious and politically-correct, patronising even. Well I think it's perfectly valid for white people to make measured objections to blacking up without risking being accused of taking offence on behalf of black people. I regard your blanket and unqualified characterisation of white objectors as unfair. I was saying that plenty of people,black or white, may object to the practice of blacking up without actually taking offence, instead taking a reasoned and objective stance. You weren't allowing for that.
