So, he's not worried about us peons pulling back the curtain and finding the wizard is a troll. All he cares about is that we go see his movies, help him buy another home, and accept everything he says as gospel. Oh,yeah, and adore him too!!
As a Texas lawyer, I will represent anyone in a Texas state or federal court against Moore IF they can bring me a valid legal claim. The problem is almost no one has standing to bring a suit, and Moore likely isn't amenable to jurisdiction in Texas (state) courts. For Federal, you'd likely have to go to either Michigan or New York, unless there is some personal jurisdiction in another state. A movie he produced being shown in several dozen Texas theatres doesn't make the minimum contacts necessary, and he I doubt he's been anywhere near Texas (at least for a long time) for fear of getting shot.
