I’m not sure I understand the complaint. Is it because there is an actor playing a veteran? Or is it the very idea that a veteran might want to go vacation in a place he once fought in a war? Or is the way they have the veteran speak offensive?
Would it matter if the actor was actually a veteran? If he was a veteran that had actually stormed that beach?
The letter back was pretty funny though, saying they read your letter but not in any way responding to your complaint.
The add plays on the returning veteran theme without any actual references to WWII or D-Day. I don't think that it disrespects veterans and their sacrifices because it seems to target more the last few years of movies and advertisements that dwelled on WWII and The Greatest Generation (To cash in or as an homage?)
