Mocking the weak and stupid is universal human behaviour. So why is it global news when a young woman is ridiculed for asking an ill-informed question on Twitter?

"Is Wimbledon always held in London?" asked a 21-year-old Tyneside resident and Sunderland FC fan during the finals. She thought Wimbledon might have been the name of an itinerant sporting event, perhaps like the Olympic Games. Her tweet was retweeted more than 7000 times, she copped abuse aplenty -- and then deleted her Twitter account in shame.
