According to this update just now, the classical music public radio station WDAV, in North Carolina, will not dismiss Lisa Simeone from her role as a freelance (ie, non-employee) host of an opera (ie, non-political) program carried by NPR, just because she has also been a spokesperson for the Occupy DC movement. The reports to the contrary over the past 24 hours boded ill for all who seemed to be involved, starting with NPR -- though, who knows, their sizzle might increase the audience for the next few installments of World of Opera.
It looks bad enough that Paul Robeson (Wikipedia pic) was blacklisted as a singer for his political views -- and at least that was on accusations of being an actual Communist during the tensest Red Scare/ Cold War era. Are we really going to start pushing people out of roles like hosting an opera show, because they side in their free time with a movement that an increasing number of mainstream politicians have said they endorse?
For the moment I won't go through the whole parsing of what outside roles are and are not appropriate for mainstream media figures. (You could look 'em up in a book!) The rules are and should be different for full-time employees of NPR than for a contractor like Simeone.* And they obviously should be different for news reporters, or editors or analysts, than for opera-show hosts. Whatever version of the rules you might come up with, there is no sane version of them that should have led to a panic over Lisa Simeone's role on a music show.
