There will probably be a few gays who flaunt themselves or openly hit on the straight guys just because they feel they can. They will be wrong and should be punished for causing any disruption.
There will also most likely be some straight guys who feel that they want to preempt any "flaunting" by those that do come out as gay (just saying they are or bringing a same sex date to a command function) or those they suspect are gay. They will be wrong and deserve to be punished.
And I am almost positive that the first time something happens in a conflict area that involves a unit with an openly gay guy, whether it be a death or something else negative, it will be blamed on having an openly gay guy no matter what the details of the event really are. I hope and pray I am wrong or that there is enough counter evidence to prove the allegations wrong.
