99 A love capable of transcending borders is the basis of what in every city and country can be called “social friendship”. Genuine social friendship within a society makes true universal openness possible. This is a far cry from the false universalism of those who constantly travel abroad because they cannot tolerate or love their own people. Those who look down on their own people tend to create within society categories of first and second class, people of greater or lesser dignity, people enjoying greater or fewer rights. In this way, they deny that there is room for everybody.
