Bumper sticker

I saw a bumper sticker that said "One Gay at a Time."

I'm mystified.

Only have sex with one gay at a time?

Exterminate them, one at a time?

"Cure" them, one at a time?

Sell them Amway dealerships? Timeshares? Win their votes?

Never hire a decorator while you're having your hair done?

Maybe it applies to schools or military units. Straights may use the showers or locker rooms in groups, but gays must go singly.

As I said, I'm stumped.
