It's not inherently bad. Some people just don't enjoy fictional stories and that's okay. Maybe you prefer to focus on factual information or other forms of entertainment. The important thing is that you do what makes you happy and fulfilled.
That's a very broad generalization. Some Christians might be more focused on religious texts, but many do engage with fiction. Fiction can be a form of escapism, a way to explore new ideas and cultures. For example, Christian readers might enjoy historical fiction that depicts different time periods and the role of faith during those times. It helps them to understand the past and how faith has been relevant throughout history.
Some men might find non-fiction more practical and applicable to their lives. Maybe they think fiction is too imaginative or not relevant to real-world problems.
