It hasn't been normalized just yet. But Western society is socially, culturally and politically geared towards enshrining 'victim minorities'. It has a long history of victim worship (Christianity, communism, socialism) and in each of these traditions the 'oppressed minority' eventually becomes the oppressive minority.

With trenders it's an extension of the rainbow-activism machinery and a trashy form of adolescent rebellion that got supercharged by Big Tech money & clout, and of course the political machinery of the DNC (which seeks to utilize the victimhood dynamic to win elections).
