Human beings traditionally have shunned others who are different because of their skin color, religious beliefs, or social status. Tragically, all too often, these differences have provoked hostility and bloodshed. Such has been true of many who have encountered Jews over the centuries. In the last few decades, however, the world has witnessed a remarkable transformation in attitude, even though fringes of hate groups still persist. We have discovered that differences need not be threatening. Rather they may be positive and may even enrich interpersonal relations. Jews and others can fully embrace their own unique identity, while reaching out to those outside of their own communities. Indeed, boundaries need not be barriers.
