Ridiculous Ignorance

I have had absolutely enough of a certain person. Just how do you correct a Chinese person from Tianjin, China about her "dialect"? It just makes him sound and look stupid. I know how Shanghai is pronounced and I even know how to speak their dialect. Seriously, the Shanghai dialect is so bizarre that it's like a new language of it's own. Maybe killing something would make me feel a bit better. Yeah, an anti-China person would know more about my own home than I do. I think not.
