That's not an unfair point, but this is where I'd distinguish the Nebulas from the Hugos. The Nebulas are supposedly the industry's picks for best SF novel of the year, like the Oscars. Whereas the Hugos are, by design, populist. If a shoot'em up action movie was truly my favorite movie of the year, I'd feel no guilt about voting for it as "fan favorite," whereas I might be taken aback if it was nominated for an Oscar.

So if I am pro-gun rights, I guess I should vote for Larry Correia? :o Seriously, it's a SF award, not an election.
