I gave this topic and OP seem deep thought. Back in the mid 1970s I had a smart Jewish friend, Chuck, who attended Univ. of Michigan as a zoology major. After he graduated there, we both ended up at University of Florida. Chuck went to UF Med school.
Since then, in 2014 I finally made it to Michigan for my first and only time, stayed a couple days on my way to Madison WI... and not for a visit, more for a work-related project. Now factor in, I consider the 'No Whites Allowed Space For Social Justice Activism' a ridiculous request. I don't consider myself White or Black. I just don't have a dog in this fight. I decline any invitation to join in.
That said, I have two more semi-related comments: 1. I believe Towson University graduate and White Activist Michael Heimbach would have some helpful advice. 2. If something similar happened at the University of Florida, I would have keen interest... and feel utterly confident both Florida Senators, Bill Nelson and Marco Rubio (both of whom attended the University of Florida), would quickly step in and orchestrate an end to the nonsense.
