The CK ad evokes child p*rn*gr*phy, which is why it was so controversial when it came out, even the print ads (which were basically just stills from the videos) were controversial. It's got this whole suburban sexual predator vibe to it, an older man "videotaping" very young looking models in a seedy looking room.....The funny thing about it is that there isn't anything obviously sexual about it. There's no nudity, no mention or depiction of sex, the models are obviously of age (one of the guys even said he was 20), and yet people found, and clearly still find it very provocative. It's funny what your mind can do, no?
The Tom Ford one is just a closeup of a crotch. There's nothing lurking beneath the surface, nothing disturbing going on, it doesn't stir any feelings of discomfort or provocation. It's just nudity.
Which of those two things is more offensive?
