A commonly agreed statement is: What we do defines who we are. That's kinda what you just referred to. Anyway the point is we gotta be already defined like what is called a prepsition. What you eat defines who you are. How many breaths you have per day defines who you are. Your wife's height * weight * 3.14 defines who you are... etc...

Feeling comfortable or not within your fellow people depends on a lot of complicated factors, language barriers, working environment... You love Chinese? You hate Japanese (just assuming)? If you live in China and unluckily died in a bank robbery, guess what nationality the man who shot you probably had?
