it's unfair to treat these kids badly
be welcoming and supportive and you will be surprised at what you will learn about the world and about yourself
Well, I think the problem just shifts. It never really ends. I've heard accounts right here in New Jersey where children shout racist slurs from the windows of their speeding school buses at my friends from India. How would those kids feel if someone yelled racist slurs at them?
I think we are all racists to some extent. However, I think most of us are tactful enough to not just yell out slurs for no reason at bystanders. It is sometimes easy to look at one's children and think "Oh they are so wonderful. I am sure they are not rotten to the core."
Middle school was terrible even though (thankfully) I was not attacked based on race. Children are evil and mean. They will attack each other with whatever they can find. Children have no problem being hypocritical. They will yell racist slurs and will complain when someone yells racist slurs at them.
This has nothing to do with race or ethnicity, but more pragmatically has to do with "outsiders" arriving and disrupting the local economy and social structure. I'm not saying it should be prevented, but you can't just say it's benign either.
If 37,000 rich people flocked to Vancouver from another part of Canada, and were mostly white, the majority of the issues being raised would remain the same.
Your anecdotal story about growing up around some of these kids is not invalid, but it ignores the larger social impact of recent events that have nothing to do with kids, but more to do with their parents' money.
