The anti ORM movement convinced only a few interested database users.
It's because of the Django docs that I've learned about a few of those awesome fields types.
IMO this was because they were too dogmatic and ignored the things ORM's did better, focusing on performance that didn't matter or on issues that come up even when you don't use an ORM (n+1 in the architecture).
That said, I don't think anyone that hasn't learned SQL really don't understand their ORM either. It's one of the fundamentals that any developer should know before they ever write production code.
