This may seem a tangent, but bear with me. You make an interesting point. Your view should be considered.

You look deeper into the mentality us vs them behind this meme. You identify that as a possible strategy to keep people apart. That is something worthwhile considering.

Now, problem is your post is hard to parse. You have what amounts to a whole paragraph with only one period. My suggestion: break information into small chunks. That greatly helps your readers. It allows them to become more engaged with your content.

Now, leaving that aside. Thanks for trying to reason through this shallow us-them mentality.
