Yes, personally I knew that. But I still feel that using it accompany photo is definitely a dog-whistle.And it's important for those of us who understand something of etymology - which include Ms. Vine and the Mail subeds who wrote the subhead - not to get carried away. The words niggle and niggardly have nothing to do with racism. The Mail is so full of any number of egregious examples of racism, sexism and any other kind of prejudice you can think of that you don't need to go inventing slights that at worst will be designed to attract the attention of right-on useful mugs for the Mail to laugh at.
And even forgetting the n-word, it's an unpleasant word to use in this circumstance. It says "something worries me about this union, but I can't quite put my finger on it". It's like when people (lead by Trump) said Hillary wasn't presidential. What they meant - dog-whistle style - was that she didn't have a penis. But they didn't say it, so they couldn't be called on it. And if Ms Vine says "I have a niggling doubt about this union" but don't say it's because of her ethnicity, then those who are uncomfortable with it will understand it as that, and we can't call her on it, because she never actually said that race was the problem.
Aside: "dog-whistle" is an Australian term, and I am unjustifiably proud that the rest of the world is using it now. I could give two shoots about the Ashes series, but I happy this phrase has currency.
