The girls will always post those things thinking they are meaningful, which they are to them. They will never experience any of those the same way that men did in a war. Those are two distinct cultures. Neither will ever overlap. You are close but you are still missing it. Look at it again Paramedics and cops and the like .. Thats heroism but its more voluntary. Thats just experiencing effects of something like 9/11. But thats nothing compared to WW2 imagery. Where you had to hold your best friend's guts in from shrpnel. Where you had to hold their hand and tell them everything will be ok knowing they were dead already. As bullets were wizing by and you knew you might be the next to go. Pulling your friend out from under gun fire. Yes firefighters go into burning buildings, but they do it with special suit knowing that they are backed up by trained indviduals. nothing compared to storming the beach in D-Day where 100 thousand soldiers fell. You are comparing apples to oranges.
