You're just late to the party if you think the vitriol is coming from only the side that actually laughed at the jokes. What you are seeing is the rebellion against the first threads on this, where the first lady was called a whore and admonished for unsubmissively interrupting her husband.
That thread got pulled after over a thousand posts of that or I'd prove it.
Maybe I missed some of the comments on those threads. On the threads I've seen the majority is just saying they disliked a couple comments. The vitriol seems to be coming from those who say these people are like the Taliban.
