Discrimination exists in different forms around the world. There are many studies to explain why it is so. Some researchers believe that discrimination has appeared with the emergence of nation-states; others emphasize social psychology, and many others think economic crises have been the main reason. Whatever the cause, discrimination still exists in many countries, in many different forms.

Let's take, for example, what one of the candidates of the U.S. Presidential race is saying. He says he is willing to govern a nation which symbolizes diversity, pluralism and freedom, yet he believes Muslims should be banned from the U.S. Perhaps he imagines that all Muslims are recognizable by the way they are dressed, or maybe he will order security forces to storm the mosques and place everybody in custody. What about Muslims he will not be able to recognize at the first glance? Maybe he will ask the Secret Service to determine who is a Muslim, and then he'll put these onto ships to send them back to their countries of origin.

We are talking about Donald Trump, as you may guess. Thankfully, he is not yet president, and all he says are, for now, just election promises.

In Wales, asylum seekers are being made to wear colored wristbands at all times, otherwise they will not be fed. Those people have left their Middle Eastern countries to save their lives, and in the U.K., they are not allowed to work and earn money; so if they want food provided for free by the government, they have no choice but to wear these wristbands. It reminds one of what people wear in all-inclusive holiday villages, but the context is terribly different here. These wristbands mark asylum seekers out and further stigmatize them in an already hostile environment.

We'll probably see more stigmatization like this in the near future. Why not leave permanent marks on people's bodies, so the locals can always identify those foreigners? It seems that everything is now allowed to draw unwelcome attention to the refugees and make them feel ashamed.

Maybe at some point governments will develop more "creative" methods to force these people out. They will, for example, close their eyes to racist organizations so these may frighten foreigners as much as possible. If refugees are being constantly attacked in the streets, in their homes, or if their children are beaten at school, maybe they will decide to return to their ruined countries.

A number of European countries have decided to confiscate refugees' personal belongings, their jewelry or cash when they enter those countries. Those European countries say they need those resources, thus refugees will contribute to the country where they now live. One wonders if those European countries, who act like highway robbers, really need these few golden rings or earrings in order to preserve their economy. The purpose is probably to put psychological pressure on those refugees, and to deter them from coming to Europe.

In another European country, male refugees have been banned from municipal swimming pools after complaints of sexual harassment: Why do they treat every refugee as a potential criminal and put a general ban, instead of punishing only those individuals who have harassed women?

These refugees are desperate people hoping to get a new and better life in a foreign country; then those do everything possible to reject them. They can sometimes be extremely creative in finding methods of rejection. Maybe they should concentrate more in solving problems in the countries of origin of the refugee crisis; so that those refugees will not have to leave their countries in the first place.
