I have experienced racism many times in my life. It is never pretty when it happens and usually comes without a reason.
I remember when I was about 5 and waiting for the school bus with my older sisters and brother and we would get called " chink " by the other kids. Of course we tried to explain that we were not Chinese, therefore, using the slang / inappropriate word "chink" to describe us was incorrect. But to them, if you're Asian, you're a chink. So, we just pretended to ignore their taunts. Their behavior was never corrected or punished because there were never any adults that accompanied them to the bus stop. But if there were, I'm sure they probably would not have done much.
I've had more experiences since.
What's been your experience?
