Then you are simply defining deviancy downward. If this is not soft-porn, then what is? Full frontal nudity? Actual penetration? S&M?
The bottom line (no pun intended), is that bodies that are naked all except for nipples and pubic areas, erotically posed, ARE soft porn. Four naked female bottom's lined up in a row are intended to be highly erotic. If you did not take it this way, then the developers of the advertisement would be deeply disappointed.
I find that what many people consider to be "soft porn" or no porn changes drastically when their 8 to 13 year old sons or daughters are alongside them viewing the...er.. event. Also, it's one thing to ban pornography in it's various forms, and it's another to ban PUBLIC pornography in any form, which can be viewed by innocents.
Innocents deserve the chance to remain innocent, until their parents can introduce mature topics at an appropriate age. My children, for example, learned all the glories of oral sex at a very young, precocious age, because of a pornographic, sex-addicted President who sullied his office.
That's why words such as "soft porn", "porn", and "hard core" must mean something more than "I like it", "I like it a lot", and "I freakin' love this sh*t so leave me alone you prude!!". Words create laws, and good laws protect innocents.

"Then you are defining deviancy downward. If this is not soft-porn, then what is? Full frontal nudity? Actual penetration? S&M?"
I am only "defining deviancy downward" if I (not you) consider the nude female body to be "deviant," which I do not.
Depending on the venue, full frontal nudity MAY be considered soft porn. In other venues, it is art - in others still, it could be educational. For a billboard, that poster is sexy, not pornographic.
Also, I have three children - daughters, aged 26 and 18, and a son, aged 22. The eldest daughter has some reknown as a stage actress and model in the mid-Atlantic states. My point is this: I've raised three children,...and my views on what constitutes porn, soft or otherwise, haven't changed through the process.
The accepted definition of "soft porn" is depiction of sexual activity short of penetration.
Your definitions of "soft porn", "alone", "sex", "is", etc, are not relevant.
