Discrimination is one of those confusing concepts that drives us all crazy.
It is something negative when it is an illegal act of the government or a public power, since it is an attack against the principle of equality before the law.
Yet, when we speak of discrimination between private people we tend to miss the simple fact that we all do it, all the time.
We all discriminate when we choose our friends or our partner, when we apply for an specific post, when we hire a worker, when we decide to have a tuna sandwich, when we cheer on our favourite team, when we buy a book, when we marry or when we decide to spend a week in Brazil and not in Canada.
And we do it according to criteria of beauty, race, culture, kindness, money, intelligence, etc and other very "selfish" reasons.
We all do it every day and it is our right (without prejudice to the fact that by doing so we could be maybe a stupid or a bad person in some cases).
So, discriminating CV with picture or discriminating interview for a job ?? ...yeah !! isn't that the main function of a CV or an interview ? .... to discriminate !!
