Parents? Plural? I doubt it.
Wait, don’t tell me, an ultra Maga white supremacist?

I guessing, but it looks like the parent-teacher conference resulted in the student being punished in some way, loss of cellphone, etc. and the student decided to punish the teacher for his giving a bad grade to the student.
Now, here in my county, the student would be automatically expelled from the public schools system for attacking a teacher, and if under age 16 be required to take classes at a separate county school for ‘bad students’ where the parents are required to provide transportation, etc.........................
“Plural? I doubt it.”
Nah, in a world where the plural is redefined as the singular (they, their), why can’t the plural (parents) be redefined to mean the singular?
The modern rules of today’s grammar are a lot more complicated than when we studied them in fourth grade.
