What is the problem here? An infringement on speech?  A waste of resources?

Just let students know that their interaction with this team is purely voluntary.  Then armed with that knowledge, their response to this team can simply be to decline to be "educated".

Or perhaps the UO could waste even more resources (i.e. unnecessarily ramp up the cost of a college education) be creating still another Offense Response Team - the sole purpose of which would be to remind offended students that offense, like beauty, is in the eye of the beholder and that taking unnecessary offense is an offense itself - a habit often exhibited by the uneducated.
