I had always assumed it was a sailor kissing some random nurse, not a "couple". I thought that was the point of the photo -- a random act of joy akin to kissing a stranger on New Year's Eve or something, only more so.
That's what I've always taken away from the image. The complaint doesn't stink of feminism so much as just how annoyingly litigious people are nowadays.
