The featured article at Wikipedia today is about the Ecole Polytechnique Massacre in Montreal. The events almost 20 years ago became symbolic for two Canadian groups which have referred to the massacre as a turning point event: feminists highlighting this as emblematic of male violence against women, and gun-control advocates who successfully lobbied for more gun-restrictive laws after the event.
Nowhere in that article will you read that Marc Lepine, the perpetrator of the massacre, was born Gamil Gharbi, son of an Algerian Muslim immigrant who believed women were inferior and repeatedly abused his wife in front of his son. Huh. Wonder why.
