Frau_Phillips has a problem with that too, but I was trying to explain to her that those advertisements change based on the content of the page you are viewing. If you open a thread about say, Obama and Clinton, you'll get Obama and Clinton advertisements. If its a thread about Timbuktu, you'll get an ad for cheap airfares to Timbuktu.
Subsim isnt about promoting one view or the other, so I shouldnt worry too much about it.
