That's a pretty good point. My own feeling is that idiocy like this is the result of our having become a society in which so many people self-validate through social media. Maybe not even a majority of people, but since those who do are by their nature the loudest, and since social media itself is, by its nature, the sort of thing that rewards the loud, we get a culture war in which the weapons are things like "ROTFLMAO!" and "TROLLED!"
(Disclaimer- I am not on any social media, unless you count this site as one. And I don't mean to disrespect people who do use it, because it is, in this day and age, a necessity for a lot of people in business and a convenience for a lot of people who just want to stay in touch with friends/family.)
