Do you think banks are going to happily accept meaningful regulations to prevent another economic collapse? Or the healthcare industry will accept meaningful regulation that lowers medical expenses? Or the rich will accept laws that empower unions and reduce income inequality? They will all fight tooth and nail against these things.
Do you think white nationalists will happily accept a society where non-whites, women and immigrants are treated as equals and treated with dignity?
Sometimes life is zero sum, and for one person to win another person has to lose. Sometimes doing the right thing means bad people get angry (ask someone who fought for civil rights in the 1960s about that, about whether the white nationalists in the south happily accepted the civil rights movement without complaint). Welcome to the real world.
