You're right, I guess "overly masculine" is the core of what I didn't understand. I don't know what that means, and while I can imagine someone being disappointed if they couldn't find any books with masculine characters and themes (which I think we agree are not hard to find, even among award nominees), I can't imagine someone finding those but thinking "but these aren't overly masculine, that's what I want". If you have some examples other than Cormac McCarthy books I think it would help explain the concept.
Haven't read any of those Nebula/Hugo books, but there are shifts in style and emphasis that are very indicative of the author's gender. Not at all universal, but given a thousand words of writing, I bet I could identify the author's gender at 80% accuracy.
That wasn't what I intended to convey. They're altogether not published to the same degree they were.

do a search
> I don't feel like I'm having any trouble finding masculinity here.
What were the exact words I used? They're right there. Read them again.
