Reddit reviews Zero Tolerance Discipline Policies: The History, Implementation, And Controversy Of Zero Tolerance Policies In Student Codes Of Conduct

The left rarely advocates for zero tolerance policy. It's old and archived, but the Geek Feminism Wiki lists Zero Tolerance as a red flag, preferring instead "A scale of consequences that takes into account multiple factors, but which includes the possibility of complete and permanent exclusion when that is the consequence that is called for." Guidelines on how to write a Code of Conduct for a con will rarely mention "zero tolerance" at all. Papers have been written on how zero tolerance disproportionately affects minorities, with the case in front of us being an example. There are books exploring zero tolerance policies, and while I haven't read that one myself, the summary doesn't put such policies in a good light, and ends with a recommendation for a three chance system.

There is no one in this thread arguing that this policy is a good idea. This is entirely a misapplication of what leftists actually argue. Zero tolerance policies are a lazy excuse for avoiding nuance, pushed largely by school administrators who are using their brains less than the students they're supposed to be teaching.
