But you could also argue that the fact that it even turned into a "thing" in the first place is evident of another group of biased folks at work.
You can't control what the other side does - you can only control what you do.
I've laughed and joked around at a funeral - it is natural - I got some laughs delivering my father's eulogy. It breaks the tension, and you can't just be somber all the time - I'm sure BHO barely knew Mandela, if at all. The point is, if you dignify every attack with some sort of defense, at a certain point, it gives it credibility. Michelle looks angry to me all the time, unless she's forcing a smile on. It would be no surprise that she's in a foul mood after a 16+ hour plane ride, Air Force One, or not, I sure would be.
This pretense that they're superhuman - that doesn't serve them well. If you want to take an example of what W did right is that he at least appeared to be just another doofus, goofy slob like the rest of us. Part of the reason Kerry did so poorly in 2004 is that he acted like he was better than the rest of us.
