Gay marriage compared to a a bisexual marriage is like comparing counterfeit money to genuine. It debases the value of the institution by rewriting it basic meaning. If accepted where is the objection to polygamy, or marrying ones pet goldfish or even oneself (for the truly narcissistic) for that matter.
...or gays in the military...
Military units are forged from the first day of training to think and react as a unified group. They share a common experience in everything from sleeping and eating to personal sanitation. Military Special Forces units, even though made up of tremendously resourceful individuals, are inculcated with a unity of trust in their fellow unit members to the degree that they would give their lives to save that of a team member. The military has no use for personal privacy nor "lone wolves".
Gays currently serve and do so under the conditions described by keeping their orientation to themselves. Under those conditions they can and do serve with honor. Putting your sexual orientation out in front by declaring to the rest of your unit that you are gay will destroy unit cohesiveness and put a severe strain on the necessary trust between unit members.

Agreed...I’m sure I served with many gay men and there were many lesbian “Waves” in the barracks down the street. But nobody went around pointing it out.
