Remember the movies back in the day? Cowboys were generally the good guys. Unless they wore black of course. They didn't want no steenkin sheep around to screw up the grazing land by chewing the grass down to the ground. Remember too, the sheep hearders were like farmers in that, they liked to put up fences.
By billing this as a cowboy movie or western, the left is just trying to screw up the image of another American icon.
