It seems like we're converging on the question of what the Social Contract should be for a society that has some mix of hetero- and homosexuality in it. In the U.S., if a hetero couple are about to part, a light kiss is completely within the norm in most places and pretty much unremarkable unless it turns into a spit-swapping session :smile:. However, a homosexual couple that also perform the light kiss may encounter a chilly reception (if not worse) in many places in the U.S.. I think the reason for this is that, in the abstract, most hetero people don't really think about the physical aspects of homosexual relationships -- out of sight, out of mind. But even a kiss, if same-sex and obviously one between lovers, is enough of a jarring sight to remind some otherwise uncaring heteros what goes on behind closed doors. And contemplation of that act is uncomfortable for many hetero folks, especially right-leaning ones.
I don't know that there is a solution to this that makes everyone happy. There certainly has been an effort to make same-sex contact more normative through depictions on increasing numbers of cable outlets and network shows. Potentially, that could, well down the road, make right-leaning heteros less, er, squeamish about seeing same-sex contact in public. But I think it will be difficult to tell for some time whether that will work to any dominating point in the society we have.
I know this can go both ways -- that some gays find hetero "breeder" contact hard to stomach. But I'm firmly convinced it is much more weighted the other way, merely by the dint of pure numbers. Whether the squeamish reaction is primal or learned is probably hotly debated in some circles.
