I think what is apparent to me in the video is that the teacher is telling students how to think and feel about specific types of eye color in students. And the students then run with it because they are being told to do so. Children look to adults and authority figures for direction in how they should think, feel, and view the world. It is our responsibility as adults to help students develop appropriate, acceptable views and practices of the world. As an educator, it highlights how much of an impact I can have on student views and racial biases. If I expect my students to be accepting of all individuals and I act in that manner, I am more likely to see students doing this.
I also think this reflects on how authority figures within our government can impact how citizens view racial inequalities and practices. Like children looking to adults, we look to our government, business, religious, and societal leaders to give us guidance in how we live day-to-day.
