My experience with saints fans over the last 5 years is that they are incapable of being objective about their team, on the average. There are of course exceptions, quite a few.
But they're some of the least informed fans in the league. It mostly stems from the 'we get no respect' angle. Therefore they have an over inflated sense of self to compensate.
I'm a member of the bears, Vikings, giants, eagles, Commanders, texans, 9ers, chiefs and falcons boards as well as the Saints. The saints fans, IMO, are a step down when it comes to what they say amongst themselves.
