The concept of the 'Last Man' describes 'normies' like you and has nothing to do with race per se. Last Men are simply hedonistic, materialistic, mediocre, passive/submissive consumers whose life is simply work, i.e. the average person today. They will never excel at anything, and never rebel, for they are by and large contented with their lot in life. They are what the 'far-Right' do not want—and have abysmally failed to prevent—people to become.

Think of some obese moron lounging on a sofa eating Cheetos in front of some television upon which some nonsense entertainment is displayed. He swaps in between doing this and the 9-5 ratrace, and it's all his life will ever be. I don't have any real opinion on Nietzsche's politics, but he would have had nothing short of sheer contempt for this kind of person (as does the 'far-Right') if he saw them today. It's obvious that humans can be, and have been, better than this, despite the contemporary glorification of mediocrity and the sheer contempt for success as merely being the result of 'oppressing others' or 'privilege' or some such nonsense coming from the Left. George Floyd became deified by the masses precisely because a lack of quality is now itself regarded as a quality (he's a 'victim' of 'oppression' and 'privilege' rather than a drug-addled dangerous criminal who threatened to shoot a pregnant black woman).

Nietzsche already saw this 'transvaluation' of values happening in his own time, but this process has become much more entrenched over the past 121 years since his death. The signs of this are everywhere and are far worse than the examples he himself provided: 'fat is beautiful', 'fatphobia', 'black is beautiful', 'criminals are the real victims and police are the real criminals', the body positivity movement, plus-size models, 'Eurocentric beauty standards', 'White privilege', 'defund/disband the police and replace them with councillors/mental health professionals' and all this other nonsense. Fatness is true fitness. Ugliness is true beauty. Stupidity is true intelligence. Failure is true success. Evil is true goodness. Interestingly, there are literally Biblical quotes warning this would happen, e.g.

Woe to those who call evil good and good evil, who turn darkness to light and light to darkness, who replace bitter with sweet and sweet with bitter.
