Revealing, publicly, the private affairs of a private citizen, IS a violation of decency.
You would prefer every type of sexual practice out in the open ? There are far worse things out there. . .
Violating Privacy, even of practices you find abhorrent, is STILL vioating privacy. . .
That would be a damn sight better than conferring legitimacy to abhorrent practices because you'd be more comfortable treating the practitioners as innocuous as long as they don't rub your nose in it.
Unfortunately, as we've seen in the past twenty years...your nose WILL be rubbed in it.
