I understand that, and Narnia has been discussed along with other secondary topics. You asked why Brokeback was getting so much attention here, that's the reason. It's a film with a political agenda. And this is a (primarily) political board.
I'm not entirely sure why you're splitting hairs here. The answer to your question is fairly obvious.
Not splitting hairs, just wondering. The answer to my question is not obvious, because people post about movies and books they enjoy all the time, with no political content--ever notice the "Bloggers/Peronsal" and "General/Chat" links on the side? I don't find many discussions about a movie people here love, only endless false info about the finances of a movie they hate.
