I don't know if the op is a troll or not but I have seen QF staff being a little on the rude staff to Asian passengers.
This was on a HKG-SYD flight and there was a lot of overly loud speech directed towards some of the Asian passengers (By the FA's) as well a bit of eye rolling.
Of course though this could have been due to any number of issues on either side and I don't think is indicitive of a racist culture within the airline.
