Pettiness is the rule of the game with those types, I suppose. Now I have my share of criticisms against GRRM, some of which I've just posted here, but the disgraceful attacks on the guy by so many talentless SJW nitwits actually kinda makes me indignant on his behalf, even though I also know he had this coming after sticking up for them & against some of the last guys to accurately call out the Hugos. There's so much that has been said and can continue to be said of ASOIAF - that it's not nearly as 'realistic' and 'accurate' as it claims, that it's so flawed compared to LOTR that it's rather laughable to call Martin the 'American Tolkien', that the grimdark fantasy trend it started hasn't necessarily been that good for the medieval fantasy genre, that it will never finish, etc.
But I think we can all agree that, for better or for worse, the dude did actually put in the effort to churn out five increasingly huge books and a fantasy world with decades-long influence on the genre, on top of his earlier works, and that said literary universe also spawned a TV show that was actually pretty good for its first four seasons. None of that's true of this Natalie Luhrs & others like her. I don't think they've even demonstrated a decent enough take on his writing and politics (I disagree with GRRM but I've yet to find any reason to imply he's a fascist of all things) to be able to criticize either, much less to do so with such unhinged vitriol.
Now it's not entirely unexpected that a gaggle of talentless dangerhairs, whose works are nothing (sometimes literally, as in they haven't even started publishing a damn thing yet) by comparison and whose influence will not last past the end of their blogpost, would dare try to tear him and other sci-fi & fantasy giants such as Campbell down in a vain effort to chase clout & pretend like they showed the (literally) big mean old white man what-for. But it is equally hilarious and maddening all the same, like watching a rabid howler monkey flinging its own shit at...well, I wouldn't say the Mona Lisa, the Sistine Chapel's ceiling or even a Norman Rockwell painting would be an accurate comparison here, so let's say something painted by Jackson Pollock. I mean really, just who do they think they are?
