Here’s a good article on How to Spot Truth in the Sea of Lies, Rumors, and Myths on the Internet.
Political memes are the worst for lies that spread like wildfire. I’ve seen them lying for both sides. For instance, both of these are lies from the last presidential election: http://www.snopes.com/1998-trump-people-quote/ and http://www.snopes.com/hillary-clinton-stupid-quote/
Just take a moment to check. If you don’t have a moment to check, maybe you don’t really have the free time to be posting, anyway. Go to the original source if you can. If you can’t, just google some more sources. Check if you’re on a satire site. Think about if the article/meme/blog post in question is just confirming your own bias and you’re not thinking it through.
