Have you ever considered the fact that because clearly much of the world's population _does_ in fact comment on these posts, that _they_ have said normal "human behavior" and not you or I? We're the outlier on Facebook.
While several million is a lot, yes, it is a far cry from the 7B people in the world, or the just shy of 3B users FB claims to have. The question is how many ignored that post; it could very well be that they out number the ones who commented, and those who comment are the outliers.
It could also be sockpuppets are commenting to drum up the numbers to make the post look hotter than it actually is.
I don't get why you're being down voted. It's a fair argument. We really don't know how many ignored the post.
Yes, since Facebook picked to promote it, probably a low percentage ignored. But what is "low percentage" to Facebook algo?
Maybe usual average is 90% ignores without "engaging". With this one, "only" 60% ignored.
Which means the majority are not triggered by this sort of thing.
This is only speculation, but just to illustrate the argument may be valid indeed and these networks like Facebook end up giving an impression that something is "normal" across humans, but they're actually not.
