Racism is a concept that is still alive today.
It's based on the thought process that someone can be better or more valuable than someone else, and uses loose racial classification to group this idea.
If you look into race from a scientific, genetic point of view it doesn't exist. People from the same race can have less in common than people from different races.
So why does this concept still haunt us?
I think the concept still existing is the result of confused concepts.
Allow me to explain.
For racism to be true the idea of someone being better or holding more value than someone else also has to exist. This idea is the backbone of racism. You don't get racism when someone uses the other side of this polarity, you get something just as ugly though, superiority.
Racism is based in a dichotomy of good and bad or better and worse and it takes an equally basic thought processes to access an emotional connection to the concept of race. Because it doesn't truly exist.
The idea of race was manufactured by people who didn't know any better and they paralleled it with better and worse without noticing. There is no way someone can be better than someone else in all the aspects and experiences of life, and there is no use shoving a basic notion of skin color in the mix to add to the false concept.
Race is an outdated concept and only the uneducated can view it, they see it because of personal emotional reasons. They rely on the concept of race for identity because their current identity is fragile and anything will be used if it gives a feeling of stabilization.
