It may seem like bigotry at first glance, but regardless of any member's personal distaste for homosexuals, the fact remains that if a unit can't operate like a team and trust each other on and off the battlefield, the mission itself is at stake.
While there are any number of solutions, the most amicable one, while keeping military goals in mind, was DODT and that's why it was implemented.
