"You can judge a man by his enemies"...to to to true!
My guess is, his detractors that say he shouldn't have been allowed to hold that there, are the same that call people bigots and intolerant for saying the Mosque shouldn't be where it is...
You have to love that kind of hypocrisy.
To me Beck showed poor taste in the timing and venue: he did it on the anniversary and at the same place where Martin Luther King Jr gave his historic " I have a dream..." speech. Beck didn't say anything to directly contradict that message but he didn't say anything in support of it either. Palin, I don't think you get much more of a polarizing figure in the US these days (including Hillary Clinton!), and she (along with Rand Paul) has become an icon for the regressive side of the Tea Party movement.
This could have been staged a week earlier, a week later or someplace else and I don't think it would have been as big a deal, but on the anniversay of an iconic speech that promoted equality and acceptance, it just feels wrong to me.
