Before Facebook there were just fwd fwd fwd fwd emails. I’d rather crap be posted on FB then cluttering up my inbox.
My FB is only open to a very small handful of friends/family (less than 50) - I was prone to fact checking before that was even a thing…so have always been the one to find the true (or more true) information, and often will say something a bit lighthearted like “although it sounds plausible, it’s just not so” or my more recent go-to “if only that were true” and then provide the link to the true (more true) information. Occasionally I have had to be straight out “that is simply untrue” (ala when a very dear friend posted an out-of-context Margaret Sanger quote) – then I’m pretty clear and have used a wonderful photo I found, it’s a vintage advertisement lookalike (I actually think it’s a Rockwell) with a father and son, father says “Now son, do you know what you’ve done wrong?” and the son saying “Yes sir, I shared something on Facebook without checking facts and encouraged bu!!&h!t to propagate, leading to the dumbing-down of humanity.” – I don’t “really” care if I hurt someone’s feelings by calling them out, I do however care enough to stop the misinformation.
I think you mean “aisle”, not isle. 
I mostly look at cute extended family photos on Facebook. If I’m sent wrong info, I send a correct snopes link to the sender and reply all if it was sent to many folks.
Well, someone did mention snopes to her before I had a chance.
" Imagine if (pre-FB) you kept getting letters from a friend filled with newspaper articles, ads, fliers for various causes and nothing else. "
LOL. We had an uncle who did this. My mom quit opening his letters. That was over 30 years ago.
If it is something that’s been debunked by Snopes or Politifact, then I’ll post the link. Sometimes I’ll point out that the source is not legitimate (this I’ll only do to my liberal friends because I don’t want to start a war). It really depends on how egregiously wrong it is, how well I know the person, and if I’ve got the time.
One friend of mine sent me a private message asking me to never call out her mistakes on her timeline, but to instead send her a PM. Her public persona is important in her career. So, now I send her PMs – because I think it’s all important to her public persona/career to be factual. She’s removed several things after I’ve proven they are either incorrect or from a dubious source.
Here is a question for those who call out friends for posting misinformation on their social media…do any of your friends who have been presented with facts actually believe you , or the links provided or do they continue to believe what they posted in the first place ?
I find it difficult to convince those who are stuck on a concept / idea.
Usually if I comment on political posts, I do it to show that not everyone agrees, and not so much to convince the other person. At least on my newsfeed, certain viewpoints seem to be overrepresented because the people that hold these views tend to be more active on Facebook and aggressive in their discussion.
I just post “nope” with a Snopes link.
I have no problem publicly shaming people who share fake crap and hope that maybe it’ll signal to others that it’s fake, too.
I’ve been deleted by more than one person because of this. Fine by me.
I have had no issues pointing out posts which were factually incorrect and have done so many times. Sometimes this was in the form of posting snopes or relevant articles/quotes which debunked the posts.
Other times I’ve gone toe to toe debating them into the ground.
One memorable example was a infowars conspiracy theory follower who kept asserting there was no legal support for birthright citizenship. I kept giving him a bit more rope by asking him to cite evidence before springing a Cornell Law School link to the 1898 US vs Wong Kim Ark case which is the foundational ruling confirming the constitutionality of birthright citizenship and the unconstitutionality of government agents attempting to unilaterally strip Wong Kim Ark or any naturally born citizen of immigrants or anyone else with the exceptions of ambassadors or other employees/agents of foreign governments.
He ended up shutting up right then and there to the applause of mutual friends who felt his arguments was based on little more than what he heard from Infowars and similar sites.
I do nothing but know a friend that refers folks to snopes.
After citing snopes, most of my FB friends delete the post.
I think we all need to fight fake news. You may not convince the poster but you will set the record straight for other potential readers of the post. All the “alternative facts” out there, from any corner, are a danger to our society and to democracy. Let’s force people to think more critically. We’ll all benefit from that in the long run.
Some of the people in my FB feed think snopes and other fact-checkers are liberal liars, so most of the time I don’t bother. But if I think someone is well-intentioned but passed on something without checking, I do correct them, and I post it publicly. I just linked to snopes regarding a post that claimed “the government” was taking away our subsidy for diabetic blood test strips (Australia did that; that’s where the story originated).
^yay, that “Snopes is liberal liar” argument make me nuts. Like Politifacts it cites its sources and cites where fake things originate (like that story you referenced.). Snopes and Politifacts are solidly sourced. It has nothing to do with political leanings.
The exact same crowd that thinks objective sources are lying, unless they happen to agree with those sources, are also the folks that disagree with science if they don’t like what it says. That is fine unless and until they are put in positions of setting national policy and then it is alarming. A senator or repr from Utah had a town hall meeting in which a girl asked him if he believed in science. Good question, young lady!
I’ve often find conservative publications or think tanks to quote and cite and will point out the political leanings of the references cited. Makes it kind of hard for them to argue with that. 
Before this year, when the $h!# really hit the fan, I would try to remind other people (and myself) that something that sounds too good to be true, probably isn’t true. Also, something that sounds too bad to be true, probably isn’t true. Whether it’s a free Caribbean cruise offer or NJ people happy about 9/11, it deserves - at the very least - further inquiry before deciding.
None of my FB friends or friends of friends have deleted erroneous posts. They either acknowledge and thank me and/or others for the corrections and responsibly own up to their mistake or in a few rare cases like the Infowars conspiracy theorist double-down and go on a long rant long on unhinged emotion and hyperbole and devoid of evidence from credible sources.
And the rest of us would respond correspondingly.
