As someone who studied math in college, but can hardly string a line of code together without making 4 trips to stack exchange or some documentation, this was a very good explanation of why math is actually really exciting.

I definitely did growing up in elementary school. Every morning, during the school wide announcements, the principle or whoever was talking on the PA system would recite the pledge and students were pretty much expected to stand and put one hand on their chest and at least listen if not recite it.

It seemed to taper off in my middle school years, and basically only ever happened at football games once I was in high-school.

This is all in a fairly blue area of a generally pretty blue state.
