Yes, it's an "opinion," and as such deserves fair scrutiny. Well, I've scrutinized it and found it baseless. Neither of us know whether the man is "sincere," but we can certainly evaluate his views on America's political predicament, its outline and its sources.
As for my "comical predictions," most of what I've believed would happen over the last several years has, and this isn't because I'm a seer but because it's pretty obvious to anyone paying real attention to the big picture. Perhaps you are specifically referring to my allegedly "apocalyptic" remarks about the possibility of secession and civil war in our future. Yeah, I've made mention of that grim scenario for a while now, and I see nothing to change my mind. I'm not a pessimist by nature, just, alas, a realist. Beck has, charlatan that you believe he is, laid out the lineaments of that big picture, and it's sad that you don't appreciate his unique use of the medium for a couple of years in the best interest of his nation.
