Id heard about this, but hadnt given it much thought. It seems that someone at the University of Oregon complained about one of those magnetic yellow "Support Our Troops" ribbons (like the one on my car) that was affixed to a truck driven by a campus maintenance worker. The truck belongs to the University, not to the worker. The University decided to enforce a law prohibiting "political" statements on publicly-owned vehicles.
Fair enough. Im not sure that Id like to see a lot of state-owned cars, in Oregon or elsewhere, serving as rolling billboards for the personal opinions of the employees. (How many members does the AFSCME have?) But to be "fair," shouldnt the University of Oregon also ban the posting of personal political opinions on other forms of University property, like faculty office doors?
