Baldilock picked up on this story from David Neiwart's recap of a bunch of similar troubling signs. She has the right reaction.

It’s likely that I would personally not care for Mr. Cowell’s work of art, however, who would I be to deny him (or Ms. Haigh) the right to display it? Who are these “men” who would physically assault a woman for exercising her right of free expression on her own property?

(One of the commenters in the previous thread judged it to be cowardly to go to the police under these types of conditions. I suppose that Ms. Haigh should have attempted to beat her attacker—likely much larger than she—to a pulp. The likelihood that I might have tried to do such a thing in her place is irrelevant. She did something much more intelligent: she told others and got the attacks publicized. However, were she allowed to and inclined to keep a fire arm in her place of business, such Brown Shirts—that’s what they are--might have thought twice before attacking her.)

Public discourse is circling the bowl and knuckleheads on both sides of the fence are making it happen. Do we on the right want SA-types to promote our causes? Do you on the left want SA-types to stand for what you believe in?

I know what it’s like to live with violence right outside the front door. If reasonable people do not want this whole country to slide down into such an abyss, we have to take a stand against those who would see it happen, no matter whose "side" they're on.
