Satement from AIM June 3, 2020, which I agree with:

The American Institute of Mathematics stands in solidarity with the Black community and with peaceful protesters across the nation and the world in outrage, grief, and despair over the brutal police killing of George Floyd and many other Black individuals before him.

We believe that mathematics is a fundamental human endeavor, and we reaffirm AIM’s commitment to diversity and inclusion as essential to the health and development of our discipline. For many of us, the beauty of mathematics often provides a silent refuge from the chaos of the world. Let us not retreat from this moment, however, but instead commit to draw upon the power of mathematics as we work together to bring about systemic change and greater justice in our society.
