Yeah, because students won't turn that into your permanent nickname mr. peepeepants.

They will, but you won't have to register as a sex offender. Major difference in life outcomes.

What crack are you smoking? You simply get up and walk to the restroom like any normal person would. Teachers can largely be ignored, if they physically do anything to you it's lawsuit time.

Depends on your school, class, and colour

No you can sue them in pretty much all cases if they put their hands on your kid.

I think you are dreaming.

Have you done that? Sue the powerful (a school board) from a position of powerlessness (black working class in the ghetto)? Probably not, unfair question. Do you really think it is a realistic prospect? Really?

There are toll-free hotlines for reporting teachers engaging in child abuse.

Obstructing a child from using the bathroom who needs to is a form of abuse. If that teacher then physically restrains or otherwise contacts/touches the child to prevent them, especially if it culminates in their wetting/soiling themselves, this starts resembling something along the lines of sexual abuse.

If there's one thing the USA can be relied on it's both society and the law leaning heavily in the direction of protecting the children, to a fault.

This situation is literally just a phone call away from completely ruining the teacher's career if not life.

Have you any data for how well that works for poor black children?

I hear people with theories, but child services the world over are famous for nice theories and systematic abuse. Especially for minority and poor children

So could the former because where I'm from there's a certain amount of times you can not be in a class (without a doctor's note that justifies it) before you face expulsion. IIRC that number is around 20 classes per school year, so that alone brought me to 1/20th of an expulsion.

And being the teen that I was, it's not like I had an otherwise perfect attendance in any of my high school years.
