@autonomousapps I have a lot of similar experiences. While I was doing an Environmental Management program, I had a lot of classmates who kept doing "we know better than everyone" attitude toward sustainability within varying communities (and many of my classmates were particularly hostile towards indigenous people).
And when I did my teaching program, listening to the ways in which so many people thought we should punish children (with people who wished corporal punishment was still allowed) was... It was a whole bizarre thing to someone who was like "I think we should talk with kids to help them understand the impact of their actions, and I think we should mediate between two kids who have more minor issues with each other and be there to help if they need us to guide their future interactions." And being told that kids simply can't do that made me... just confused (because I did it as a kid, the people around me were capable of it, and I saw kids doing it in the course of working with them).
All that to say, those memories also crop up for me as I watch people march toward fascism.
(Also, I'm with Irenes. It's not silly, even if it is idealistic. I also was silly when I entered my teaching program because I wanted to change it from the inside out, and I learned that was impossible. I just use that energy somewhere else now.)
