To the best of my knowledge, those two tent preachers ARE their jobs. Who's going to "fire" them? Kind of like Michael Moore on the other side of the looney coin. You can boycott their product--I personally don't buy a lot of Pat Robertson stuff--but that's pretty much it.
And of course, you can discredit them all over the internet, which seems to be pretty effective in some cases.
