The human being generally interprets what he sees, reads and feels influenced by his particular interests and desires. Our opinions and decisions depend on who they are directed to, because if they have to do with ourselves or our loved ones it is very different than if they are directed to any other person. Such is the human nature, it is normal that our experiences, affections, education, religion and everything that defines us as individuals, affect our way of seeing the world.
This is why I firmly believe that objectivity does not exist or is very difficult to find, instead we see subjectivity in all the stages lived by the human being. I understand subjectivity as everything that is expressed, felt and manifested and that involves our feelings and personal experiences.
The same experience lived by different people, have different consequences for each one and each one will have different opinions about what happened. Religion, culture, sex and other factors influence this.
That is why people who see things in black or white and believe that their opinion is always correct, realize at some point in their life, that there are other colors that are also valid, that what is really important is respect for opinion and feelings of others.
