Your rant applies to literally the entire internet. Even this site.
What? Why? Because you say so? No, it doesn't, "literally the entire internet" (holy hyperbole, Batman) or even this site, do not pretend to be a better alternative to actual social interaction.
FB didn't make them that way. A portion of the population has always been mindless gits.
Oh really, well then what is stopping those "mindless gits" from infesting this site as they have the Facebook? I mean you don't even have to register to post here like all those so-called "social" websites.
Facebook didn't make them stupid (duh), but it deliberately provides an environment fertile for such stupidity. It is a business after all and is there to make money. And every businessperson worth his/her salt knows, the bigger your targeted demographic, the bigger your profits.
So in conclusion, Facebook was tailor-made to cater primarily to the mindless masses, exploiting their stupidity to make sure that they spend as much time on Facebook as possible. It is, hence, such exploitation, such making of profits at the cost of a massive negative social impact worldwide, which makes it evil.
