From the article:
[Zwerg] was drawn to the Freedom Rides after he was assigned a black roommate while attending Beloit College in Wisconsin. He grew to admire his roommate and was shocked to see how the young man was treated by whites when they went out in public together. So he volunteered to be an exchange student at Fisk University in Nashville, an all-black college, for one semester. He wanted to know how it felt to be a minority.
This guy and so many like him were seriously brave. He thought he would lose his life but he pressed on in a cause he believed in. Go check it out.
