This thread is a fascinating tour in what Alliance posters are deliberately ignoring. On one hand they want to ignore the game material showing things like Theramore's involvement in the war or earlier things like Northwatch aggression on the Barrens predating Garrosh's invasion on Ashenvale or, even earlier, Varian being the one to declare the war back in wrath.
So one could think that it's just what @
Skytotem said in the very first reply, i.e. how the book doesn't address Theramore's behavior in Cata. As in, one could think that Alliance posters are simply going by the book alone while ignoring the game.
Except... at the same time there's the story of innocents and children being killed by the mana bomb pushed as the main reason why Theramore is bad.
You know, the innocents and children that left Theramore via ship because Garrosh deliberately sat at Theramore's gates for a week doing nothing, giving them ample time to leave. Which they did, leaving only those wanting to fight behind. Which made them no longer mere civilians but a militia. And militia members are combatants and as such valid targets of war. And all of that is covered
in the book.
So Alliance fanfiction peddlers aren't just ignoring the game material and focusing on the book alone, which is already wrong since game material is still canon. No, they are doing something even worse. They are cherry-picking the most convenient aspects of both the book and the game. Though credits where credits are due, it is nice of them to expose themselves this hard.
