They hinted, pretty strongly, that Rudy was homosexual.

Fruity Rudy? Remember?

If he was, is body-building how to survive being gay in the Marines? No one would pick on or bully someone who could beat them up? The series seemed realistic in some ways and I wonder about the real Marine Corps. Someone is suspected of being gay, is called names, but that's as far as it goes; he is not ostracized, picked on, bullied or continuously harassed until he's run out of the corps.
