That's a false generalization. Also, Elit said he was unbeatable vs Proteus. Which was fair enough. He hasn't actually mocked phiwha, who has up till now played the bank in Havoc. I think you've read too much into things.
I don't see anyone mocking Sanctuary or Rage for failboating this age. But it is natural that Absalom garners its fair share of haters, it's been around for a long time and much of its history has been marred with their hypocritical stances and holier than thou attitude.
