I find it hard to take seriously the notion that anybody serious is arguing for "let's go back to all white dudes" as a response to DEI. Sure...it's going to happen because nepotism and cliques aren't going away. But on the whole, it seems people want to move towards competence/merit being the only factors in play.
Will it get there? Time will tell, but there will invariably be issues. Your execution can be wrong, even if your philosophy is right. But if your philosophy is wrong (we need x% minority engineers, x% trans engineers, x% female engineers), you'd be hard pressed to avoid bad implementation.
