But in my case when I was a kid,

"Ignore those bullies, they say."
"They will get bored and leave you alone, they say."

I actually foolishly believed those bloody words.

The oldest example of bullying in the book. Single out the one who is different, call her names, run her down, and try to get rid of her. It's not about being "politically correct." It's about being mean, and nothing else.
