This meme is a joke, however, it deals with a very serious theme. The image of the woman  confused by the math problem is used to show that something has very little logic. In the 1800s, many Americans were migrating westward, so they relocated Native Americans. Native Americans were not only relocated, but also put into camps where they were forced to speak English, and even punished if they spoke their native language, in order to become “civilized Christians.”  This meme is used to show how little sense that makes. Christianity has themes of spreading kindness and “loving thy neighbor” yet the “good Christians” instead kill and ruin Native American culture.
