A lot of people post memes to Facebook. Some of them are funny, some of them are tongue-in-cheek humorous. Some of them are intended to be serious.
The main challenge is that many of the serious ones are politically polemical, and most of the polemical ones are wrong. Actually wrong is being too polite. A lot of the memes are based on bullshit and lies. Here’s a great example:

This is an excellent example of a meme stuffed full of lies. It is yet another attempt to claim that there is a significant voting fraud issue in the USA. There are plenty of studies already out there to prove that those sorts of arguments are grounded mostly in bullshit, but that does not stop partisans from “joining the dots” via yet more memes. Politifact has demolished every assertion in this meme if you click on this link.
Stay away from political memes this election season. Most of them will be total crap.
