"When I was growing up, I wore the hijab in high school, and I faced lots of discrimination and being called a terrorist when I just came here."

"But when you don't have that, young people feel displaced, they feel devalued, and that's not really good, because young people will look for identity wherever they can find it."
There is no national record of crimes connected to ethnicity, something advocates would like to change.
