Encounters with racism?

My first encounter with racism was something that I refer to as "the oven incident".

It was in....first or second grade I think. I was about...7 or 8 years old at the time.

This kid was going around telling everybody in class that his grandfather had told him that all black people were white people who had done terrible things and were put in ovens. If he or any of his friends did something bad then they'd all be put in ovens and turned into black people too. Being A) In Alabama B) a predominately white school and C) one of the few black kids who was in the class, you can probably guess how well that went.

I was small, I didn't understand, "kiddie cruelty" came into play and naturally I went home crying my eyes out. I asked my grandma and grandad (cause I stayed with them at the time while my mom was in the hospital) what we all did wrong. And that was when I learned what racism was. My mom found out shortly afterwards and pitched a 20 ton hissyfit

So I was exposed to racism fairly young and knew what it was from there - hence the question:

What was your first experience or exposure to racism (be you black, white, asian or otherwise)? If your first experience wasn't the most vivid in your memory, then what was? How did you deal with it? And lastly, how does it affect you at the age you are today?

Jam it back in, in the dark.
