I don't agree with that either. You don't need polymorphism for OOP.
It's
quite restricted without it, but you can still program with objects even
if you're restricted to something like D's structs, so you're still
doing OOP.

No. That is glorified procedural style. 'Objects' as in 'OOP' carry data
and _behavior_, structs don't (except if you give them some function
pointers, but that is just implementing poor man's polymorphism.)
Having some kind of dynamic execution model is a requirement for OOP.
There are no two ways about it.
Well, I completely disagree. The core of OOP is encapsulating the data within
an object and having functions associated with the object itself which operate
on that data. It's about encapsulation and tying the functions to the type.
Polymorphism is a nice bonus, but it's not required.
I think the model you're discussing is often called "object-based".
