Am Going back to China

I've just been told to Go Back to China: the second time in five years. This is posing quite a conundrum for me because I don't come from China: I was born in Vancouver. And even at that, my family roots are in former Eurocolonies Hongkong and Macau (as opposed to Communist Red China). My Vietnamese GF similarly has a conundrum: she comes from Việt Nam, and going back to China is even more difficult for more reasons than I care to relate!

Now I can't really take a bunch of yahoo Nainaimo boys in a pickup truck all that seriously, but when will hurtling racial epitaths out a window at 50km/h stop being fun?
