The polite thing to do would say you won’t be coming and not elaborate further.
If you’re not ready or able to move on from the shitness of high school, you don’t have to go. I didn’t attend mine either. But the way you’ve framed it here says to me that you want conflict, you want to pick a fight with someone over something ten years old…and ultimately no one involved, including you, would get anything good or healthy out of picking that fight.

Fuck polite, bin it unanswered. You owe them nothing.
