It would be inappropriate to ask your gay neighbor not to attend family events. A polite way to create a boundary between your family and the neighbor is to suggest alternatives, such as alternate events or locations, or offer a friendly explanation that some topics may make family members feel uncomfortable and suggest an alternative activity.
