Ok I'll bite.
"If you are going to play the crash statistics argument at least factor in total fleet hours flown, miles flown, passengers flown"
What is safer B747-400D or the B747-400ERF?
There is no argument, you can selectively use certain statistics to play the story you wish to hear - your inclusion of "passengers flown" is to use a apples verses oranges principle. But when we break that down to the 747 pax/freighter number of passengers is clearly not relevant - but you do have a statistical valid point.
