This foxnews coverage gives a bit more info. The mallfolks claim that the men were doing more than sitting in the food court, they were “disrupting shoppers” and a complaint was made about them. And 3 months ago 20 peace activists were asked to leave the mall (and did so without any arrests).
If we assume those “activists” were staging some sort of demonstration for peace, and that the most recent 2 were “activists” as well also attempting to rally support for the cause, I think it would be clear that the mallfolks were well within their rights. Malls are intended for commercial transactions – folks not there in that pursuit may disrupt it. Whether non-commercial activity is loitering by teenagers, rallying by Klan members, or protesting government actions by goodhearted people, there are more appropriate forums for these activities. The mallfolks have a right to ask that it be conducted elsewhere, and to back up that request if it is refused. They have no obligation to provide a forum for that activity.
That said, I realize that these two gentlemen alleged that they were doing nothing but wearing the shirts, and that asking them to leave because of only that certainly smacks of over-reaction. But given the earlier incident the mall is probably on “orange alert” and poised to Fife-style “Nip it! Nip it in the bud!” And we have a few hourly employees who are trying to do the job they were told to do.
I would have left and not come back. But if they were doing more than sipping an Orange Julius, they should simply move their vigil elsewhere.
