I can see a connection between you not reading ASoIaF and you believing it would have been accepted poorly if written by Vox Day. Frankly, and I say this as a big Martin fan, A Game of Thrones is ten times better than anything else he's written before, and A Storm of Swords is in some ways probably better than any other fantasy novel I've read. If all you know of the books is their pale and increasingly distorted shadow that is the HBO show, I can see why you aren't very excited about it.
Yeah, I haven't read the books. Don't get me wrong I think the series is very good for what it is.
But I also think that if it didn't have "blood and boobs" it wouldn't be anywhere near as popular as it is. It would make a very interesting PBS kind of thing (though without the money for all those actors and sets), but it wouldn't have the mass audience it has without all those hot young things popping up nude in Littlefinger's bordello or whatever from time to time. (You might catch an old guy on the "throne," but not flashing a lot of skin.)
And it is a similar thing with the violence.
My point being I don't think Martin is indulging his political sensibilities or worldview in this work (unlike Goodkind). It's a pretty reasonable stab at telling a realistic story in this kind of world.
But if Vox Day (insert anyone with views you find as reprehensible) had written something like this? The usual people would be all over it. Incest, gratuitous violence, subjugation of women, etc.
