This is an excellent analogy. It speaks to a lot of things I’ve considered about nationality and expresses how complex identity is, and why it’s so important to be flexible as a result.
I am a Canadian-born recently made dual-citizen of the UK, temporarily living with my American wife in Australia and likely to relocate to the US before the year ends. My maternal great-grandmother was Metis and my paternal grandmother an English war-bride. I have a heritage of ravaged first-peoples and colonising whites, the privilege of being English speaking and Middle-class and the challenges of being queer and a non-conforming woman.
I don’t doubt that anyone reading this post has just as complex a mix of influences, background and experience.
