Not only that, as you can see on this video, the yeshiva is openly messianist (the yellow flags in the yeshiva's Lag Ba'omer parade and the "yechi" yarmulkes worn openly by some students), and the parents of these messianist kids are often the schochtim and mashgichim working at Agri Star. And, as you can see at right, the yeshiva says, Postville is "Sholom Mordechai's [Rubashkin's] Town."
