An obvious question which begs an answer: I am a heterosexual and can refrain from boinking my wife or even overt PDAs in public all the time. Why can’t the homo crowd abide by the same standards of courtesy?
Overcompensation.
It's not enough for you to accept and tolerate homosexuality. You have to "celebrate" it.
There can be no "yawn, so what?" when someone comes out of the closet ... they have to be acknowledged as "brave heroes".
My theory on this dynamic of overcompensation -- Every living thing reminds homosexuals that their basic drives are not congruent with the design of life because every living thing comes from a heterosexual union.
So, to compensate for the continual reminders of their desires being dissonant with the design of life, they need continual and exaggerated reassurances. Plus, they are pouty little bitches.
I've seen you wife... (Finish this joke....) lol
