I remember we had one Chinese kid in our junior high school around 1963 and he was razzed mercilessly. I’m sure the WW II effect was still prevalent then even though he was Chinese, not Japanese. He went on to be a fantastic concert violinist.
Kids were razzed, taunted, bulled for all sorts of things — gangly, socially awkward, fat, skinny, ancestry, zits, weird music tastes, unathletic — anything out of the mainstream. It’s surprising any of us survived!
We had several albinos that were harassed often.
