David Weber is a conservative and a monarchist, but not alt right. Kind of gives Tolkien vibes sometimes, honestly, in that you’re pretty sure he supports the Divine Right of Kings but wouldn’t be okay with war crimes. I’m pretty sure he doesn’t like gay people but he doesn’t go out of his way to beef with them either.

John Scalzi doesn’t have any damage I know of.

Dennis E Taylor literally has some characters talking about “both sides” in a recent entry with a plot about shape shifting lizard people controlling the government, but the Bobiverse made me think more classical liberal than ancap wingnut, it’s possible he just doesn’t know that lizard people is conspiracy code for Jewish people. Bobiverse is great regardless.

There are others. I think. Helldivers by Nicholas Sansbury Smith seemed fine but I wasn’t interested in reading past the first one.

Edit: Craig Alanson! My current favorite, ExForce is great. Mileage may vary later in the series, Skippy can get a little annoying/abusive.
