I agree with much of what you say except I'd never stand behind Fox---just on GP. they may be right about this tho.
but what I really think is that this lipsmacking blue nose attitude comes mostly from the media, Including most of all Fox! not so much from the people themselves,---because the media uses sex to sell most everything. its their best advertising tool.

If peekaboo type sex isn't kept titillating, it cancels their best advertising tool. If people were used to seeing nakedness outside of sexual context, they wouldn't get so worked up about it when they see it.

I think thats why you see its so prevalent--its not so much coming from the people, its all a big marketing ploy they flog the American people to death with.
