No, but it can be STARTED by the third grade..
All this race shit makes kids think about it. No third grader cares what their playmates look like.. Until someone plans the idea in their heads.
When I was in Kindergarden, I had to walk 2 blocks to school. On the way, every morning there was a group of black kids a couple of years older than I was and they would hold me up every day for my 5 cents milk money.
I figured out that if I walked arouund the block the other way so that I did not encounter the black kids, I could make it to school with my milk money, even though it was a longer route.
Was this racist or common sense?
