No. As noted above, this isn't about him being on TV. Look, active duty servicemen and women go on Wheel of Fortune or Family Feud all the time for Military Week or something like that. They play for various charities, and the guy who solves the final puzzle gets an extra 10K donated in his name to the Wounded Warrior Project or something. That's cool. No problem with people being in uniform and on TV in that situation because all veterans benefit from it and there's no way for the prestige of the uniform to suffer.
Andy Baldwin, on the other hand, somehow got the Navy to sign off on letting him play the man-bimbo trophy for 20 some odd desperate women to make a spectacle of themselves for on national television, despite the fact that we were fighting two wars at the time and the military is chronically understaffed on doctors. Because he went on this show, somewhere there was a guy who had to sit in the crap in Afghanistan away from his family for an extra six months because Andy Baldwin was living it up in some hacienda on the military's dime. I really don't give a crap how many volunteer hours he puts in or how many triathlons he runs. Baldwin needs to be mocked for his decision to do this until every memory he has of the experience is tinged by the feeling of being repeatedly kicked in the balls.
