"okay, so, the only reasons (not mutually exclusive) for someone wanting to join the marines right now are: they haven't considered everything, they are immoral, they are stupid, they have fallen to accept the pervading views of society, or it's the only job they can get/way to fund college. if sandgoose isn't immoral etc. then he hasn't considered everything."
Are you really so closed-minded? I expected more than that. I do not approve of everything the military does, but that doesn't mean I can't be prideful in my nation and don't want to offer up my body and potentially my life to serve it. If you don't share that pride, great. You don't have to. You don't have to risk your life for something you don't want to do. But Sandgoose's life is not yours, it's his, and if he wants to put it on the line to serve something he believes in, so be it.
