They’re cosponsoring a protest of him in St. Louis today.

Commenting on a Daily Kos post encouraging the protesting, a friend writes:

But what is most disturbing is that these protesters with bags over their heads look an awful lot like American hostages who in the next moment would be beheaded by their terrorist captors. What they are protesting is a man and policies who worked diligently to protect their rights to pose in this outlandish garb. Were they a few thousand miles to the east they would not be so free.
