We are all subject to our conditioning, and it's as easy to cleanse oneself of it as sin, even if they know better on an intellectual level. People evolve overtime and the most important thing is to change behavior, first they STFU, then they stop voting for morons, and hopefully open their hearts on their road to redemption. People try to be better, because overt public racism is seen by the majority as antisocial (it is), so it is only spoken among friends, then friends start admonishing them and they keep their tongues in check. They become resentful and complain about political correctness and such, finally some at least, evolve as much as they can.
The key thing in the above is conditioning, subconscious reactions of approach and avoidance on a fundamental physiological level that not only drive consciousness, but bias thinking by having it appear in a conditioned context. We don't think for the most part unless we are working on something real and even then... Most of the time we are rationalising "feelings" that are felt in the body and reflected into the mind where they form the basis and impetus for higher order processing by various sub networks in the brain.
Our consciousness is where we humans present ourselves to the world and there is a competition as to what gets in as thought and this driven by feelings and logical that is biased from the beginning, also there is a filtering of our perceptions of reality, to make it all fit together!
The end game is always survival and reproduction, everything else is extra or and accident.
