All teams that are successful are hated outside their fan base. If they're successful; one of the best or the best in the league, that means they're a big threat to the success of some other team. Thus hatred is born. Nobody hated the sharks before they started beating us. Nobody hates the penguins, or even Crosby for that matter, until they started getting legitimately threatening. Up until recently, Chicago was the team everyone loved to play because it was an easy 2 points. Now that they won a cup and stand to challenge for it for at least a little while, there are a ton of folks that hate the organization.
The wings have been a threat to other team's success, and that threat has existed for 20 years. That timeline is long enough for just about every team in the league to have been competitive or near the top at least once. In other words we have directly threatened (and often succeeded) at stoping just about every team from reaching their ultimate goal during a period when they actually stood a chance at winning at least once. We're widely hated for this reason.
