Discrimination at FH Odendaal Hoerskool

I have a serious problem with how FH Odendaal Hoerskool treats it's black (African)learners as a parent I know our children sometimes misbehave but the schools code of conduct that says late comers should be sent home that's criminal at best for one my son uses taxis to and from school and South Africa is not a safe place especially for children so no learner should be expected to put his/her life at risk because if they're late at school they will be sent home ,are teachers and principals not there to safeguard our children's safety during school hours and what does the Gauteng dpt of Education say about this practice of FH Odendaal Hoerskool sending learners home because of late coming(this happened to my son who's in Grade 12 , the taxi driver was looking to fill up his taxi leading to my son arriving 5 minutes late at school and deserving to lose the whole days work according to Mr Vermeulen so the teacher sent my son home and my question is shouldn't the learners right to Education be paramount and shouldn't there be another form of punishment more suited like detention after school so my question is why are African children still treated like this in 2023 and how will we build a united country if people like Vermeulen are still allowed to teach our children if they are still stuck in apartheid mentalities?
