Let's not for get that Frodo actually FAILED. I'd say that right there disqualifies him as a Gary Stu. Not to mention he suffered far more than any Mary Sue can be allowed to.
The opposing author's criticisms come off as really defensive. Especially Carlier's.
But what's fascinating in the book is the mangled army recruiter is a much bigger character. And he eventually explains, in no uncertain terms, is his job is not to be an army recruiter, but to scare people away.
I like that as an example of a military leader who never lost a battle SARGON OF AKKAD names Alexander of Macedon. Gee, who else is a good example?
He has it completely backwards. His flaw is that he's coming at this thinking that Starship Troopers is about the eradication of the aliens when in fact it's about the preservation of HUMANITY. Not the human species, not the human animal, humanity. And he thinks this is going to be accomplished by becoming like the bugs.
The conflict arises specifically because of the collectivist nature of the bugs. They see an incursion from a small band of Mormon SEPARATISTS as an attack from human kind against bug kind. And so their collectivist response is to retaliate against the human species.
No Sargon you're forgetting the book. They are not already at war with the Skinnies. They haven't had a war in living memory. The Skinnies are allies of the bugs. The battle in the first chapter is a flash forward.
The reason the Yellowstone "super volcano"is overdue to erupt is because it's a flooded caldera that's already steadily venting pressure. You don't need to bore holes into it because it's already full of holes. That's WHY it's so thermally active.
I mean, there are desert species of frogs.
It would be really funny if Baby Yoda talked with a totally normal person's voice. No anastrophe or anything.
