Why don't young Lebanese Muslims living in Australia want to imilate to become Aussie?

They have bizare believes, believe women are inferrior trash, bash people in large groups on their own, never get into a fair fight, carry knifes, never fight one on one. Seem to stand for everything Anti-Australian, seriously theu would NEVER get away with this in America, so why should they here? Also if they love Lebanon so much why don't they go back to Beirut?
