Those (few) nominal, temporary members of the 47% who would have preferred to be fully self sufficient probably did not find Romney's comment insulting or threatening, because THEY DON"T IDENTIFY WITH THE 47%. They probably heard Romney and said "Exactly right!"
As for Rush's comments about Fluke, they are taken out of context here. As usual. In the same little rant Rush referred to himself and his audience as pimps and johns. Were those intended as serious insults? No? So "slut" was dead serious, but those others insults were just jokes? Hokay. I have had it with people who work so hard to misunderstand Limbaugh's humor. Screw 'em.
Fluke’s a dude anyway.
