The Republican National Committee pays people to log on to chat boards that it considers "liberal" and plant and respond to messages that refute the supposedly "liberal" slant.
These include gay, feminist and African-American message boards. The plants, or "trolls," are fed information several times a day through right-wing internet sites like the Drudge Report and right-wing radio shows like Limbuagh, O'Neill and Hannity.
Apparently, the theatre chat boards were put on this RNC list for "Disinformation Targetting," because theatre-folk are considered "pink."
Those of us who remember Nixon's "Enemies" list understand that this is a mark of honor, alhtough it is exceedingly unpleasant to listen to endless right-wing drivel.
Basic rule of the Internet: Ignore the trolls and try not to feed them. At any rate, don't let them get to you.
