Well, if you look at it as it was created by Tolkien, it's definitely AuthRight. 

However, Lotr became favourite by students and like young Leftists (which is almost the same, though), for which it was like something psychedelic. If I remember Carpenter, author of Professor Tolkien's biography,  clearly, according to him, these liberals created like a magazine called Gandalf's garden. All of this made Tolkien feel discontent.


I have to say that OP's LibLeft girlfriend wasn't imbued by woke ideology, so that's why she wasn't against Lotr. Nowadays revolutionaries are in their hate against it straightforward. They claim he was racist (duh, according to their standards, even wall is racist because it is white), "Papist" (Catholic, almost got it right), heterosexual white man. To Wokes he is the enemy of the people in every way. It's great it's like that. If Tolkien would be loved by Wokes, something would be terrible wrong.

If I remember correctly, LoTR was very popular among the Hippies in America and the phrase "Frodo Lives!" had some pretty big use in the counterculture of the 60/70s appearing in graffiti, on shirts, buttons, bumper stickers, etc.   
How times change.
