Talking with some senior immigrants, I got that as they told me: without politically correct (PC), you don't have a door to go to any play rooms - never mind you want following the play rule for fair play. You think you can do better without PC but by your talent to get ahead - you're naive and so ignorant about the history of the US.
The US is like a castle, the door is selectively open to certain people. Even you're in, you're selectively inviated to certain play room. Only a few got invited to the room of King David, you may stand around there - only a few lucky souls got invited to seat by the round table (decision-making).
Be patient - it takes time to be tried out to see if you're worth trusting. Either blacks or Mexicans are the children of Caucasians. Asians are neither of both ethical groups.
Be hold. wait for your turn.
