Like when a google employee was free to ask questions as to whether it was that women don't like programming as much as men, and got immediately fired? Because of course the cause is sexism.
Like when James Watson had suggested intelligence was genetic, and if races differ genetically, so too may their intelligence... also fired from Stony Brook leadership. Because of course alleles that confer intelligence genetically are magically perfectly balanced in frequency across all races.
Not to pick on leftists for ruining careers, the right has done this to leftists as well - see David Bohm, a Pennsylvania native and at the time brilliant contemporary of Richard Feynman, who lived out his life in Brazil because McCarthyism got him.
Thing is, the left did politicize science, just read Nature: https://www.nature.com/collections/daficfhiff

DEI is essentially a commissar type system where one must pledge to the political officer allegiance to the cause, one where proletariat origins are favored over bourgeois. Trump's response is heavy handed but what is happening here is poisonous and insidious, insofar as outright hiring one demographic group over another is universally seen as evil, but hiding it behind a process of bureaucracy and good intentions somehow transforms it into virtuosity. DEI is basically a parasite that has infected many systems and hurt many people, it would be more elegant to simply remove the parasite, but Trump's tactic of taking a metaphorical flamethrower to the parasite and its host both will garner popular support given a lot of people have a bad taste from DEI.
