I think that you are wrong in general, but that parallel is right on point.
The root of the problem, which is rarely mentioned in these discussions, is that many people enjoying comfortable living conditions believe themselves to be “pure-blooded” and unable to deal with “unclean” things because of the possible “traumas”. (What is an ideal person free of “traumas”, anyway? A vegetable stoned on drugs?) You can easily see here the resemblance of a old time countess complaining about her “nerves” while her serfs do all the dirty work. Is there a natural law that says a poor grunt is bound to clean the junk from what you see on the website? Do it yourself.
The same happens with medical, law enforcement, and other professions. They are considered “special” jobs for “special” people (which is not true, the one who defines it like that is “special”). Then, any worries and doubts are neutralized by convenient “but it's their profession, they chose it, they are paid for it, etc.” This creates a stupid rift between “us” and “them”, and affects how both sides reason about themselves.
The resulting imbalance is routinely abused. Social networks are competing in presenting a rose-colored walled fantasy to their human cattle to increase yield — everyone can see they use “The Matrix” as a business plan. This creates a lot of shitty jobs where people waste their emotional capacity to make others pleased, not unlike in prostitution. On the other hand, media is hooking the softened consumer with the sensationalist outrage bait about maniacs, wars, corruption, presumed orgies, etc. To makes things worse, the limits to all of that are set not by some moral standards or concern about someone's well-being, as it is often implied, but by advertisement contracts. The bureaucratic machine decides what is “suitable” for the visitors. For example, this makes most of the talk around “Free The Nipple” moot: there is no undercover agents of patriarchy to battle, it's advertisers who bring money and judge what is unwanted “sexual content” (some might say it's a perfect example of capitalist oppression — cue “L'Internationale”).
Even this discussion is full of overreacting people. No, the video on your screen is not as “horrible, horrible” as experiencing something firsthand, nor the pain of the tortured can be compared to the pain of the random witnesses on the internet (if we don't count their own wild fantasies). If it happens, then it's no good to pretend it's not. Who knows, it may even make you think. All in all, humans don't show a lot of originality in what they produce, so the number of things you can expect to see is quite limited. I can only conclude by reiterating that knowledge is power, ignorance is bliss, and there's a lot of people who'd like to benefit from others' ignorance in many ways.
