Pointing out (in my 'BBC' accent) that I don't qualify can be amusing, as the 'reasonable' person tries to avoid saying 'but you're White?!'. Yes, with two Irish grandparents on my father's side. Which incidentally now means my British passport can be taken off me, thanks to the last Tory govt 2/3

Pre the last election, I explained the passport thing to a Tory canvasser on the doorstep as one reason why they would never get my vote. I won't apologise for taking considerable satisfaction in watching his jaw literally drop with horror as he said, 'but - my wife's Canadian - so my kids...'
