It happens during the time of economical crisis, depression, inability to realize ambitions, inability to influence the course of some events. And it often results in anti-Semitic moods of certain social groups: mostly radical working-class youth. We see this tendency now as the economical recession had penetrated into many spheres of life and touched nearly everyone, in addition there exist a conflict in Israel between Israelites and Palestinians, which still has no reference to the essence of the problem, but is used as a justification. The Jew I am belongs to a traumatized generation. We have antennas. Better yet, we are antennas," he said. "If we tell you that the signals we receive are disturbing, that we are alarmed... people had better listen." says Elie Weisel (from Wiesel: Anti-Semitism Increase, article)

Most of Jewish organizations in Europe insist to make protective legislature, use educational instruments in order to protect Jewish minorities from different forms of anti-Semitism and possible violence. Understandably a person has to be forced to escape from alienation, he has to be forced to accept general norms and beliefs as a member of democratic society, but what has to be really done is nearly impossible to do. The person has to be liberated from the chains that imprison his mind, his perception of the world and which lock his options to freedom. Anti-Semitism is one of such chains that paralyze human mind; it's not a simple stereotype. Even though it's often compared to racism, it has something more in it than a simple physical dislike; it includes mental dislike, hostility and mistrust. Its origins are in narrow-mind, philistine morality and lack of social and international experience especially in mono-national societies: Poland, Russia, Greece, and Britain.

Modern...

But it exists and its very existence may create a case when society will "sit on the gun-power barrel" which can explode and lead to visible social conflict easily.
In order to solve modern burning anti-Semitism problem, we do not need to escape from it, we do not need to ask for common sense of people and for tolerance, as there is nothing for word tolerance here, because it's not obvious why someone has to tolerate another one for doing nothing but being of different heritage. We do not have to ask the government of Israel to change its attitude towards Palestinians, as politics has to do to little with anti-Semitism. By the words of Johan Rau, Germany's president:

critics of Israeli policy had to temper their criticism -- and sometimes keep it private -- with the understanding Israelis have lived since the founding of their state under a threat to their existence." (from Wiesel: Anti-Semitism Increase)

This problem, as it was noticed by Sartre lies in the negative principles and ideals of our consciousness, of our system of values and in someway in bankruptcy of being personalities. Only reevaluation of values, change of approach to certain things, as anti-Semitism is expanded to a wider circle of objects that refer to our life will help in struggling against this stereotype.
