However you see maybe D&D is racist : elves have boni in beauty, dwarves are ugly and strong ... but any characters can choose their morale demeanor.
In fact you needed assassins as much as paladin. No true D&D party could survive without diversity of classes, races and moral demeanor.
Yes D&D is a dangerous fantasy.
It is a fantasy that states that for making a strong team you have to embrace diversity and that teach you how to deal with discrimination positively.
It teaches you that mainly your talent were random (initial dices) but it was up to you to make them a strength and it did not even mattered you were weak you could level up through doing.
Yes D&D dangerous fantasies should stop because they are turning kids in better adults better understanding that everything is a weird cocktail of luck and determinism and that we can have nice adventures out of it and improve ourselves.
Dangerous game indeed. Giving hopes to kids should be forbidden. We better need an adaptation of 1984 in AAA format.
