4chan and 8chan didn't create hyperirony (although they certainly cultivate massive gardens of it) or densensitization. Our media cycle has created it in tandem with a feedback loop that synergizes with the principle of "more people + same time amount = more hyperslices of emotion eliciting news that distort mental maps of larger-than-self situations"
You're safer at a wal-mart than prior 4chan and 8chan. But if you combine higher population density and information density, you'll get more raw events of violence even if the chance of experiencing violence has gone down.
Imo, there's a more insidious risk in allotting more powers of censorship to entities who are far less subject to reciprocal investigation. Think of 9/11. If we had done nothing, we would be safer and more prosperous today. We let the fleas provoke us into gouging untold amounts of flesh to stop itches.
Edit: A more simple way to phrase it is that hyperirony and the lack of "proper affect", which is really what people seem to be most horrified about, is a defense against the 24/7 atrocity exhibition which turns emotion into banality.
* - Note that more people, especially younger folks with their hyperbolic tendencies, and anonymity means more raw sociopathy and psychopathy being displayed in relation to those events. It's at least partially a function of the numbers game.
These aren't exactly organized bands of people funneling in millions of dollars for carrying out actual training and misson planning/execution. They're watering holes where disaffected elements of society hyperbolically play up various happenings.
Just take a step back for a moment. We have an increasing population and increasing saturation of that population with streams of data. When something happens, we know with a speed that is uncommon in human history (to be euphemistic about it).
More population = more happenings = more things to emotionally charge people in the same 24 hour frame. Even if population increases by a bajillion, we still only have 24 hours in a media cycle.
Even if the per capita incidence of violence decreases, a rising population means more slices of highly charged emotional manipulation within the same media cycle.
Edit: So instead of increasing population, resultant increasing pop density, increasing information density, and a myriad of clusterf* systems running haywire (even in an era where we're safer than even 20 years ago)...4chan and 8chan are the devil and satan for allowing people to shitpost in a hyperbolic hyperironic manner?
