Well, I noticed that the headline of your post reads: Misinformation On Line: One of the Main Treats to Humanity. I assume you meant "Threats", not "Treats" - unless this is a Freudian slip clueing us to your subconscious belief that online misinformation is a treat because "ignorance is bliss". It's also ironic that the absence of one letter in a word can distort the context in which it appears, so it's important to correct typos and proof read to maintain credibility in regard to being detailed-oriented.
I can only speak for myself, Troy, so to me there was nothing shockingly revealing about these articles to a person like me, a natural born skeptic who's been around a long time, and who questions everything.
On line, if anything sounds too fishy, I go to Snopes.com and get the lowdown. I've always dismissed conspiracy theories and I take infomercials promising miracle cures with a grain of salt. On social media I consider the source of articles and videos and check to see if they are from "Onion" or a liberal or conservative publication I recognize. I even click on the icons of suspected trolls and go to their homepage, where you can often spot red flags about their impartiality. This is one of the reasons I've never taken seriously what the Hillary Haters post about her because they are contrived half-truths.
As a long time reader of the Tabloids like The Enquirer, I know how headlines are sensationalized, and this also applies to The Net where articles and videos never live up to their hype, and memes are just scatter shots. So my cynicism keeps me on guard.
Furthermore, "online misconception" is not a subject I'm passionate about because, as was noted, rumors and urban myths and gossip have always been around; the net, as also noted, just spreads them faster. I still have a little faith in people having common sense and that they are not totally bamboozled. I think they choose to gravitate toward what piques their curiosity rather than what challenges their logic because they seek an escape from the real world.
As for FaceBook, it may not be a portrait of black culture, but it is a snapshot of it.
