OMG! Aren't there better ways to teach our children anti-bullying in school? A U.K. teacher has come under fire after he asked his class of ten-year-olds to write down a list of the rudest words they know. Fred Laband, a church school teacher, asked the kids to write down a list of hurtful words commonly used against victims of bullying and classify the words from 'really upsetting' to 'harmless' as party of an anti-bullying lesson. Parents were shocked when their children came home with books littered with expletives. The kids came up with words including slang for sex acts and words for male and female private parts. The words were reportedly even written on the black board. One mother says, "You don't expect your children to learn this kind of filth at school...I was disgusted." The school has since apologized.
