I'm not so worried about naked pictures of myself. Nobody wants to see pictures of a naked fat middle aged white guy.
Its the continual erosion of rights. Metal detector: Ok, quick non-invasive. Xray my bags, sure also quick wouldn't want to make it that easy for someone to sneak a gun on the plane. Take my shoes off?: Ok this is starting to get a bit silly and annoying, but I suppose i'll give you this one. No water bottles: what are you guys smoking, but what can I do to push back? Naked pictures?: No thanks, i'll go for the opt-out for the pat down, then at least it will be as uncomfortable for you as it will be for me.
If it takes a little OMG-naked to get traction with more people, so be it. It should have happened sooner but at least there's pushback now.
