This is one area @Hanna might be able to explain.
Especially considering the circumstances behind his leaving Oberlin is in dispute. He stated he left “in good standing”.
The Oberlin alum who had a class with him during the time of the flyer incident in 2013 stated the word around campus at the time was that he was expelled. A screenshot of an old local news article I saw before it disappeared stated he was forced to leave and that was a factor for the local authorities in “reluctantly” dropping charges against him.
