Slop.

I'm a centrist, teachers have systemic cop powers but there's a lot of them that are good enough and even more that aren't actively harmful that it deserves a case by case look

I disagree; OP and the most upvoted comment are definitely assholes, but the rest of the comments are supportive of the kid, confused as to what OP found objectionable or directly calling out OP for being a shitty teacher who hates kids.

I don't think you can generalize all the teachers on the sub based on OP, as bad as they seem.

Schools are all advanced panopticons. Through decades of grants in the wake of school shootings, all schools are working towards full observational coverage of their grounds. Administrations have become reliant on security cameras as a tool for discipline. Through laws like the Child Online Protection Act advanced internet surveillance systems have been deployed to districts far and wide. Initially built for censorship, they eventually evolved into surveillance tools as well, under the guise of safety. Every email sent, website visited, and every movement through hallways and in some cases in classrooms are monitored.

The prisonification of schools has been going on for decades. The last major advancement of this process was the creation of the "School Resource Officer" which is typically filled by actual cops. In some districts these cops are integrated within the discipline pipeline. They have and will continue to criminally charge students with crimes for behavior in schools, and their presence will encourage students, parents, faculty and staff to press charges against other students. It was only a matter of time before teachers became cops. The panopticon has been erected around them, and they have been transformed into its wardens.

The severity of this transformation will very from district to district and state to state. But these systems will disenfranchise kids across class lines and racial lines.
