But the person is. How come the bully can be rehabilitated in a school, but not a prisoner in a prison? You just defeated your own argument that prison can't be reformed, which I argued it could. Hypocrisy!
How are you going to screen for bullies? And are you going to deny someone an education because of a bad behavior? Then 90% of people would be illiterate. I think working on the root cause if more effective than just throwing people away so to speak or putting everyone in "jail".
As someone who was bullied for YEARS and without mercy, causing me to dive into a massive depression, and have heard of the tragic tales of suicide, I believe that if someone is bullying, they should leave the school system and be taken into a new one, one that is specifically tailored to help the bullies.
