Him being better than some contemporaries isn’t great. Still, the stories are good and generally you can take other messages from them that are decent. Like Éowyn fighting with the men despite being told her duty is elsewhere, despite Tolkien being misogynistic. He wouldn’t take out of the story the modern interpretation (even though the story that certainly inspired this is about a woman who literally becomes a man after all of this), but he himself said that readers should and will take things from the story that he didn’t intend, and that’s good.

I don’t have any particular issues with Tolkien besides that he wasn’t socially creative enough to see beyond what he knew, but that’s true for most people. He wrote fun, interesting, creative tales within that that generally have a hopeful uplifting message. However, we should always be critical of any creator of any work. We should strive to solve issues and point out flaws in order to improve our world. It can’t change the past, but it can change the future.
