Tolkien's writing was of course deeply informed by his Catholic faith, but he always resisted attempts to read his work as a religious or political allegory.
Though of course people have been doing that since, much to the elderly Tolkien's bemusement, the hippies discovered him in the 1960s. Some conservatives, and a few people further to the right, like his work and see some of their own values and priorities reflected in it. If it matters, the biggest LOTR fan I know of in British politics is that well-known right wing agitator... er... Richard Burgon.
It's one mark of a good work of art that all sorts of people can bring their own experiences and values to it, and take away their own interpretations. This is why I've never liked agitprop art that insists on only one interpretation. That would condemn us to a living hell of listening to Billy Bragg.
