I agree, but it doesn't always reflect on the parenting. I have a child who literally is perfect - to the extend that even her friends' parents are amazed. She's kind, gentle, a real people pleaser. She doesn't argue, she doesn't whine. I'm dreading her teen years, because I suspect she is going to be the worst.
I also have a ds who seems to constantly be in trouble (little things). He has a temper, impulse control issues, and get get riled up easily. He's had the same parenting as his sister (well, with a LOT more discipline and punishments, of course). They're just wired very differently.
I also have one that, after many years of getting calls from the school (a couple phone calls each year), that completely turned it around, and now is total rule follower, and goes out of her way not to get in trouble. I remember once when she was very exhausted (in a play), and I offered to call the school, and say she was sick. She was horrified!
I agree, I'd even argue it has a lot more to do with nature than the nuturing.
But when you have a child that naturally tends to buck authority or break the rules, then you have to work on fixing that. And sometimes the parent does everything they can to fix the issues and it still isn't enough. But that's not the problem with the OP. The OP doesn't want to be bothered with trying to fix her son's issues. She thinks it's the school's job. That's what I disagree with. Little things happen all the time with all kids and most teachers do a fine job with handling it in class. But when you have a kid who is breaking the rules multiple times a day, multiple days a week, it's the parent's responsibility to handle it.

I also know my kids will mess up once in a while--I would be crazy not to believe that; however I would be even crazier to not come down on them when they do misbehave--because then they would learn that misbehaving is okay which is not what my job as a parent is all about.
If we suspended kids for getting out of line or playing around on circle, we would have a very small class every day.
