So had it been an interracial heterosexual pair in the news account speaking of public kissing in terms of "We were simply being affectionate like any normal couple," you would have boggled equally and launched this thread, am I right?
Incidentally, you titled that first post "Like any other normal couple," whereas the actual quote was "like any normal couple." Your amended formulation (unconsciously, I trust) bolsters the point you wish to make. To my inner ear, "like any normal couple" lends itself to an implied distinction between the speaker and "normal," as in "We were simply being affectionate like any normal couple."
But we're all entitled to a hobby, mmoffitt, and if this kind of usage crusade makes your extremities tingle, then by all means go for it. I can't help thinking as I read your posts, though, that there's a bit of rhetorical cross-dressing going on here, and that notwithstanding your proclamations of tolerance* I hear the rustle—the swish?—of some serious gender unease beneath the fabric of your arguments.
cordially,
*"I don't object to the gay couple (hell, they could mate - er, sorry - they could do whatever they want on the airplane for all I care)" —Now where have I heard that sort of thing before? Oh yes: "I don't care whether he's black, white, purple or green!" as a rule spoken by persons to whom the "deviations" from white matter a great deal indeed, although they are uneasy about saying so.
