It used to be that you had to be stuck in bumper-to-bumper traffic to be exposed to sarcastic, misleading, and — fine, I’ll admit it — occasionally entertaining slogans about politics and spirituality.

No longer is this the case.

If you use Facebook with any kind of regularity, you’ve probably witnessed photo memes popping up like dandelions. And you may have liked them. You might have shared them. You might have even created a few. But I implore you — please stop. You’re making it hard for real communication to take place on Facebook, which is one of the few places where people with radically different worldviews can engage in honest dialogue.

Don’t believe me? I offer several reasons, with examples:

Reason No. 1: They’re often inaccurate or misleading.

Exhibit A in our proceedings is this gem above rebuking Christians for focusing on the wrong things. Now the fact is, the underlying truth behind this is something that I believe in strongly — Christians should be known more for how we help the disenfranchised than for what political stands we take. But the actual statement is just not true. Plenty of Christians line up at food banks and homeless shelters all the time — so much so, in fact, that these days it fails to even qualify as news. But you’d never know it from this meme photo, which relies more on stereotypes than actual data.

And this image is just the tip of the iceberg. With the next big story involving a church or a Christian leader, there’ll be plenty more.

And even the ones that aren’t snarky in tone can be disingenuous. If they include any kind of statistical graph, for instance, they’re bound to manipulate or distort the truth in some way. After all, there’s a reason why Mark Twain referred to statistics as the worst form of lying. The best of these are usually large and thorough enough that they require full-screen viewing to accommodate all the details. But even these should be taken with a grain of salt.

And don’t even get me started on the photos-with-long-stories-as-captions, which are often just the same recycled urban legends from email forwards.

Reason No. 2: They exist primarily to amuse or incite people who already think like you do.

Let’s be honest. People don’t encounter these photos and say, “Wow, perhaps I’ve been wrong all these years, and my long-held political and/or religious beliefs are actually dangerous and wrong.”

It never happens because these aren’t designed to engage people who hold different views. Rather, their purpose is the same as much of the partisan-slanted media we see today — to reinforce your views and help you feel better about yourself for believing that way.

Now, I’m all for exercising free speech — but images have power. And as we know from Spider-Man’s Uncle Ben, with great power comes great responsibility. And if this were only a political issue, I might not be as concerned. But in today’s political climate, where being a Christian is still associated with being Republican, these photos are making it harder for unbelievers to see the truth of the gospel because of all the political baggage.

I believe that everyone, Christian or not, has a right to participate in the political process. But Paul told the church in Galatia to avoid letting their freedom become an excuse to indulge in their sinful nature. For many of us, sharing these photos is a way of sticking it to the people who we feel are “the problem.”

As citizens of a global community, this is wrong.

Reason No. 3: If not misleading or divisive, they’re often so generic as to be meaningless.

Because “if at first you don’t succeed” at motivating your friends, maybe there’s something missing.

And that something is context. Many of these inspirational quotes and images, if they were on my refrigerator, I might find really moving. But the thing is, they would only be there if I put them there. People self-select these things. You can’t pass out inspirational nuggets like candy and expect them to be effective. One person’s inspirational quote is another person’s cheesy platitude.

And finally…

Reason No. 4: They make it harder to enjoy actual photos taken by your actual Facebook friends.

No disrespect to George Takei, the Japanese-American Star Trek alumnus whose posts get shared like crazy by his millions of Facebook fans, but he’s not my Facebook friend.

I know that in today’s relational economy Facebook friendships are slightly more meaningful than people with whom you make eye contact in elevators … but still. With so many people in my Facebook feed, I find much more meaning and significance in the large and small details that my friends post about their lives. You know, babies, vacations, meals, costumes, graduations, etc. So by constantly sharing these photo memes, you’re cluttering your feed with stuff I’m not interested in.

Because that’s the point of Facebook, right? To make connections and enjoy relationships. So if you want to be someone who builds relationships across the cultural divide, do us all a favor and stop posting these photos.
