I used to enjoy Correia's novels because they were fun and action packed, and since the focus was on those aspects, it was easy to ignore the right-wing politics that poked their head every once in a while.
By this point in the series, the smug and self-congratulatory tone of the p.o.v. character and most people he encounters (right-wing gun-nuts are awesome people, everybody else is a coward, or a liar and a pussy without honor), the Mary-Sueness of his obvious stand-in character, and the fact that a fat accountant who's obsessed with guns and writes fantasy somehow seems to think he and his politics are the gold standard for what's cool, finally got tiresome.
When I read "MHM: Grunge" I was surprised by how much of a smug asshole John Ringo seemed to be judging by his foreword, but I guess it's not an accident that he collaborated with Correia, since it's becoming apparent that they share a lot of personality traits. And not the good kind.
When most of the book is only inconsequential filler both for its own plot and for the overall arc of the series, and many scenes start feeling reminiscent of the one where his main character in "Dead Six" runs into a character who is described in a way that he's obviously Michael Moore, despite his name never being mentioned, in the palace of a Saddam Hussein analogue and expects us to find it clever because "liberals are traitors to America" or some such bullshit designed to pander to the lowest common denominator, then you know fun and entertainment are no longer the main objective.
Then I read about his involvement in that "Sad Puppies" thing, and yeah, the guy is a self-absorbed asshole alright. But hey, what can you expect from a guy whining that the Hugo Awards go to "literary works with heavy-handed progressive messages" while he writes endlessly about how liberals suck and only gun-obsessed alpha male types "like him" get things done and unironically writes quips about PETA being probably outraged because a six-legged monster freak got torn to bits by heavy gunfire in the middle of a war-zone where a battle to prevent the end of the world is being fought.
I'll probably finish the series just to see what happens, but man, more and more this guy seems to be a jerk who delights in being a troll and thinks he's much more clever than he actually is, while ironically being proud of not being a "literary" writer (because culture is for snobs and so on). So, he's a fucking idiot douchebag increasingly pandering to his dumbass core audience, and that's not funny in the current climate where American Right Wingers are doing exactly what they accuse liberals of doing: ruining everything for everybody.
