You might not have succeeded at that. You did a very good job at denigrating school though :)
Let me try to tell you my view: both homeschooling and schools have risks. A child can suffer mistreatment both at school and at home.
School however offers something that homeschooling can't: options. If you have a bad teacher, you will have another 4 which are average, and 1 or 2 which are actually decent. There will be bullies, yes, but you also have opportunities to make friends.
At home, all you have is a single adult. If that adult happens to be a psycho, there's no escape.
I say this as someone who suffered at school. My ADHD got completely unnoticed, being of the inattentive kind. I didn't know how to relate with others, I had no friends. I would pick up a book and read in a corner during recess. I got bullied. For me school was something I "endured", not something I enjoyed.
I also happen to be the elder of 4 children. My younger brothers and sister went to the same school I went to. They had different teachers, different co-students. All of them were happy at school, and they turned up just alright.
Now, my parents. My mum is ok (for someone who has raised 4 people) but my dad is a self-absorbed narcissist. My brothers and sister stopped talking to him 20 years ago. He doesn't know his own grandchildren. I still talk with him, but out of pity. There's no love left.
So yeah. I suffered at school. It happens. My siblings didn't. I think homeschooling with my mum would have been ok, she's decent. But homeschooling with my dad? I would be way worse than I am now.
So, there. Options.
