While I don't find it quite as rude to do this to men, I still think it is still a bit mean. It's pretty clear that the men were just handed a gun and told to shoot. Most of them had poor stances, standing up straight or even leaning back slightly, not spreading their feet and leaning forward. It's an elephant gun, of course it is going to have a fair amount of recoil, but it should still be controllable, albeit likely not comfortable.
