I can't answer your specific question, but I can speak of prejudice in general.
Where there are differences there will be prejudice. Even among any group, there will be a subset, your height, your hair, your socio-economic status, the size of your ears etc. Even worse among kids.
I've experienced what many now refer to as "reverse discrimination", i just called it "racism". That was life. Overall it made me a stronger person, and I also have a healthy respect for people of all colors, races, religions and economic statuses. I'm not immune to have lashed out at someone as a youth as I had it piled on me at a young age, but once you mature, you look back and analyze, "that was the circumstances".
The British by the way have long had this history. Winston Churchill was made fun of ruthlessly as an ADULT, for having an American mother, he was referred to as a "half breed". Jimi Hendrix experienced less racism and more acceptance in Britain when he went there (it helped that the Paul McCartney praised him), but, he had a horrible racist interaction with the police there.
Unfortunately it exists everywhere.
