November 16 is the International Day for Tolerance, a UN event to raise awareness of the dangers of intolerance.  The official website observes:

…tolerance is neither indulgence nor indifference. It is respect and appreciation of the rich variety of our world’s cultures, our forms of expression and ways of being human. Tolerance recognizes the universal human rights and fundamental freedoms of others. People are naturally diverse; only tolerance can ensure the survival of mixed communities in every region of the globe.

It further asserts that fighting tolerance requires: (1) law, (2) education, (3) access to information, (4) individual awareness, and (5) local solutions.
