One of Marc's readers makes a good point:
Why does the president keep making jokes about being in gay relationships with other straight men? (cf. Brian Williams joke, David Axelrod joke). It would be funnier if he had, you know, not been stonewalling on gay rights. Plus the jokes are weirdly aggressive... "I'm the alpha dog so I can make jokes about being gay, therefore you, the counterparty to the joke, are really the butt of it." Strange/gross.
Michelle gets it. But the humor is good-natured enough. We need to be a little less touchy about the symbols and more determined about the substance.
