By contrast are people who are primarily Christian, and from-that derive their political views - my examples here are Jerram Barrs (a Calvinist) and John Granger (an old-calendar Russian Orthodox).
The test I propose is to consider the reaction to the Harry Potter books among those who actually like the books - who find something to admire in them.
If you can be bothered to watch these four videos - I think you can see that the Christian-Fellow-Travellers miss the Christian-point of these books; and this comes as a consequence of their primarily political persepctive.
So what is my point here? It is that there is a world of difference between being a 'Right Wing' Christian-fellow-traveller, and being an actual Christian - and that difference includes the persepctive from which you view and interpret the world... including the Harry Potter books...
I should add that since publishing the Harry Potter books, and in her public persona and pronouncements; their author JK Rowling gives every appearance of having apostatized from her Christian faith, and indeed is in-effect an influential anti-Christian. Nonetheless, the Harry Potter books themselves tell a very different story.
