One final note about discussing Christianity on the flight deck. Over the years I've listened to people talk about politics, economics, astronomy, Investing, renovations, relationships, marriage, death, refugees, video piracy, world conflict, US elections, third world immigration, drugs in society, same sex marriage and any number of variations on those themes, etc. if I can listen politely to a socialist green voter whilst they discuss the relative merits of their world view and why they hold such beliefs why is me explaining my beliefs and why I disagree with the other person such a heinous crime?
