Insulting yourself

I was a follower of a certain BBC celebrity on Twitter.  Recently, or at least from when I had started to follow them, they had been using the word "chink" or "chinky" to describe themselves in their tweets.  The first time I saw this I was taken aback; to my knowledge the word "chink" is a racially abusive term for us Chinese.  Now here is a well known British Chinese individual, who themselves have been subject to discrimination, labelling themselves with the same word!

It is known that some people in other ethnic groups use racist words to address one another to communicate comradeship and affection, but it does not appear to me that the celebrity is using these words in this way; it is as if they are trying to making an outward statement, publicising their heritage in an audacious manner that also smacks of indifference and avengment.  To brand yourself with the words of your antagoniser, is this not an admission of inferiority? A proud, bold display to everyone that you, and others like you, deserve to be discriminated against and that your antagonisers are justified in their actions?

I'm not sure how many other BBCs refer to themselves in this way, but if one is indeed proud of ones heritage, shouldn't one refer to oneself with a little more dignity?  In my opinion, to do otherwise is not only self-defeating and letting your antagonisers gain the upper hand; it also harms and brings down an entire population, many of whom wish to live their lives harmoniously in this multicultural society that is the UK.
