“Let us be perfectly clear: behavior that promotes any form of hate and seeks to make members of our community feel unsafe and unwelcome – especially in their own home – has absolutely no place in our community,” the letter said. The joint statement was signed by school president Jeffrey Armstrong, vice president for student affairs Keith Humphrey and Denise Isom, the school’s interim vice president for diversity and inclusion and chief diversity officer.
