That is because memes are mostly used for misinformation than anything else. I use to have these conversations with a friend of mine who use to post memes concerning political subjects all the time and I asked her if she ever check if the meme was actually true. Of course she did not which I then had to send her to the topic at hand to actually understand the subject she was reposting. Memes are a nice tool that can be for fun but mostly it can be a tool for misinformation as people just repost them because they align with how they think.
The point isn't really the meme itself. It's just an example.
There are at least a few Republican talking points, that they very clearly don't believe.
Like small government, while funding the heck out of the military and the police.
Like freedom, while insisting that we should be tougher on crime.
Just the general hypocrisy and double standards, is consistently fascinating to me.
Most political memes are probably from marketing majors. Understanding how people process data is classic marketing tactics and manipulation. If you want to get something to missions of people just play to their bias and it will trend like crazy. Social Media is a marketing person dream, especially in the political climate.
I feel like this is putting too much credit on these things. A lot of memes are just things people believe anyways.
