Well- I suppose yes and no? nietzsche Was very vocal that he thought nihilism was bad for humanity and there is little of any debate in philosophy or history as to his feelings on the matter.
That said philosophy is at its core a search for truth, much the same that a scientist ultimately searches for truth. A scientist Can set out with a theory that light is a liquid and through their experiments they can disprove the thing that they believe- so it isn’t entirely inappropriate to use a philosophers work or statements in a manner inconsistent with their beliefs if one can make a case that their logic is actually proof or evidence of a different point than they intended entirely. That said- that generally isn’t what is done when nihilists or wannabe nihilists quote nietzsche.
Usually they aren’t familiar with his work beyond the broad similarities at the core of both nietzsche‘s existentialism and nihilism- both essentially hold there is no “greater power” or singular unifying rule of law or order to the human condition- but they come to different conclusions. nietzsche Can in essence on the braid subject be simplified to say that the purpose of life is that we give life purpose as opposed to the general passive nihilism which can be simplified to say that there is no purpose. The general nihilist philosophy can be said to be “do whatever you want since it all doesn’t matter..” where as nietzsche’s existentialism can be said to believe that since nothing matters one should do their best and through doing one’s best meaning is found. Vast oversimplifications but close enough for broad strokes.
