In response to a Holocaust denial ad running on the Badger Herald Web site, the UW-Madison campus is hosting two events this week. A panel discussion entitled “Journalism, Ethics and Sensitivity” will be held from 4-6 p.m. Thursday, March 4. In addition, beginning at 12:15 p.m. Wednesday, UW Hillel will hold a Library Mall event designed to remember the Holocaust. Chancellor Biddy Martin, who has a doctorate in German Studies, wrote a guest column in the Herald today on the importance of rejecting the adâ??s message.
