As far as I know, except for McKellan the cast are blessedly non-political. For reasons of self-protection, if nothing else, I think it is unlikely that they would be politically interested conservatives who would have heard of FR. I know there are a lot of us who much prefer the HH to the rest of FR, but I don't think anyone came here specifically for the HH, unless directed by a friend or relative.
Well, I did, sorta. At least, I signed up because of the HH. I had lurked on FR for years before that, but never wanted to actually sign up until I decided to post here.
It was the comment about searching for "freaky sites" that made me think of HH (no offense!) I mean, one must admit, the idea of an enclave of obsessed LOTR fans among a hard-core conservative site like FR is just a little... different.
