Those are valid points baggss, and I agree with you on most of them. I know my brother's case is an extreme, but he would argue that it is like that in the 'streets' as well. Now that could be more of an insecurity issue, as you mentioned.
But as for my Vietnamese friend, I'm not sure if I would really use the term insecure.
My parents are strong Korean-Americans (they just got their citizenship not too long ago), who take great pride in their Korean culture and heritage.
If someone mistakes them for being Japanese or Chinese, they would make sure that the person knew they were Korean.
Maybe pride is a more suitable term. Or maybe in reality, if we look real deep into it, the very fundamentals of pride can be traced back to insecurity, which gives your arguments more validity...?
Did I just contradict myself?
Well anyway, to get back on topic, as long as words are used to express ideas, emotions, and feelings, people will be inspired or offended by them.
... why is it that I can spend time writing on these forums, and have actually something to write about... but can't get motivated enough to start my list of papers due by the end of next week for school?
