I am 58 years old and many years since my last recess but I remember recess is where kids learn to deal with bullies on their own terms.
Bullies these days are not mostly the kid that walks up and slams you in the back of your head. They are kids that pound on other kids on social media.
Banning recess is just another example of how they punish everyone for the bad behavior of a few they cant or wont deal with.
Bullying isn't anything new, but we have to be a more sensitive society.
It is funny how we are told to embrace the Muslims because you can't judge them by the actions of a few lunatics, but we need to ban firearms because of the actions of a few lunatics.
