Your points make sense, and they are something to think about. I especially like the part where you talk about the blind belief in authorities. It's true that most people will believe what the government says without question. It's also the reality that human beings run the government, and we are subject to their biases if we trust everything they say.
However, you should have clearly shown the reader how this scenario limits their thinking. For example, I can say that because we don't have the full information or all the facts about a contentious political issue, we are limited in terms of how we interpret it. We can only explain what we know.
The same goes for religion. It's true that people learn religion from a very young age and due to the strong belief of those around them, they have limited information. Believers cannot tell them how religion came about or why people worship different gods even though they all have the same goal: to live a purposeful life.
The same goes for the tooth fairy. We are limited in that no one has ever seen a tooth fairy in real life, yet our parents teach us to believe in them from a young age.
In conclusion, you clearly explain how police brutality, Groundhog day, and media coverage limits our thinking. By adding the suggested parts, you can make your essay more clear, conclusive, and interesting.
