Are you just completely against the idea of human progress? Do you think we're incapable of fixing things that were bad in the past?
Both my parents were nurses who worked in psych hospitals. I can promise you people exist who need to be in there. People who are incapable of caring for themselves. People who in some cases already committed violent crimes. We need places to care for people like this.
Yes, abuses happened. So stop abusing people, don't stop caring for people who need care.
Prisons are sometimes abusive. People are sometimes put in prison for unjust reasons. People sometimes try to make bad laws to put people in prison for shitty reasons. So should get rid of prisons altogether and just let thieves and murderers do whatever they want? That doesn't seem to be working out so well in California.
At no point did I say there were never problems with institutions. I'm saying fix the problems instead of getting rid of institutions altogether.
Now, are you saying it's not possible to fix or what?
