Alfonso had hung up a Black Lives Matter poster addressing misconceptions about the movement on the seventh floor of Granville Towers West.
He was hurt and surprised to find the poster crumpled up in the trashcan.
Alfonso took the poster to his room and posted pictures on his Snapchat story. Fellow resident adviser Tyler Sharp tweeted the pictures, which have now been retweeted more than 400 times.
Alfonso said he hoped the poster would inform his predominantly white hall about the purpose of the movement.
“Being in this environment, we forget the struggles that minority groups like the African-American people face,” Alfonso said. “I thought that I wanted to be a voice here in Granville Towers.”
Out of the about 60 first-years Alfonso oversees, he said there are no black students and very few minority students.
“I wanted to expose them and make them aware of things going on — the struggles that people face and why this movement’s going on,” he said.
Allan Blattner, director of the Department of Housing and Residential Education, said the department filed a police report and doesn’t know who vandalized the board.
