From my experience, ORMs allow folk who know nothing about databases to continue knowing nothing about databases
Although the worse offenders by far are those which decide ORM = bad and bypass it at every opportunity.
Why stop there? Let's ban RDBMS. If you can't contemplate a binary file structure and index strategy perfectly tailored to your application's needs ahead of using an RDBMS, why should we deign to let you use an abstraction layer with clever query planning and algorithms?
It's all too easy to morally 'ban' people from technology and gatekeep it behind wishy-washy nonsense like "ORMs are bad for beginners."
