I can think back to high school when “cliques” seemed so damned important, “Whoooooaaa, she’s hanging with those dorks?! Ewwww! Gross.”
That’s what this is, immature bullshit. A clueless kid gets it in his/her head that certain people are cool, worships them for reasons that won’t make sense when they are older, and then does something stupid out of that devotion.
So it’s not new, it’s just amplified by social media.
I will say, it continually amazes me the way the internet is used and abused, and how it changes our lives in ways few could have foreseen. Like any tool it can be used for good or evil, but it’s such a new powerful tool that its uses are more pronounced than anything previous.
