Maybe a few naive people in the movement had good intentions but they were clearly dupes for what was at its core a right-wing white supremacist and incel ideology.
And the proof is in the pudding. Has the anti-DEI movment (and current administration) created a truly fair and equitable society that focuses on merit in the absence of gender and race? No. It has created a society in which the contributions of anyone other than white men are systemically attacked, torn down and even erased from the public record.
