1. You are raised as different. Someone is inferior, someone is superior.You need to have that in mind.
2. As long as the inferior accepts his inferior condition, there will never be a problem.
3. The problem starts when the inferior starts claiming he is not inferior anymore.Being superior is the most comfortable chair.
This claiming can also be tacit, by simple behaviours.So, when the inferior starts acting like superior, this is a problem for the superior. A fight needs to be taken, because things can't be mixed, changed!
If racism is kept in an hypocrit level, it's ok. If you get to achieve how the superior mind works, it's a big problem.
Law makers, media, inter alia, have a great contribution on this.If we keep insisting from the scratch that we are different, then we will have to be given different opportunities, to keep the different levels.
Same opportunities create same level of competition.
