The term "old fogy" is often considered derogatory, as it describes someone who is old-fashioned in their thinking and refuses to adapt to new ideas. There are, however, many synonyms for this term that may be more appropriate. For example, the phrase "traditionalist" can imply a respect for history and the established ways of doing things without necessarily being closed-minded to new ideas. "Luddite" is another term that refers to someone who is resistant to technological changes, but may not necessarily be stuck in their ways in other areas. Ultimately, the choice of synonym will depend on the specific connotation desired and the context in which it is used.
